Undefined control sequence. \includegraphics

Question

So I'm just trying to load an image into my document, and I know that the image has to be in the same path as my TeX file and it is, so I have no idea what's wrong with what I'm doing. I don't know if maybe it's my computer, my TeXstudio, or maybe some obvious error in my code, or something else. I'm aware that this question has been asked too many times, but no solution I found fixed my problem. This is the code that I have:

\documentclass[12pt]{article}
\usepackage{graphicx}
\begin{document} 
\begin{figure}
\centering
\includegraphics{figure3.png}
\caption*{Stopping voltage as a function of frequency}
\end{figure}
\end{document}

I'm new at LaTeX by the way, so I don't know if I included everything, but I think I covered everything.

I'm trying to load the figure3.png into the experiment4.tex file, and unless I'm losing it, they're in the same folder. Also, when I hover my cursor over the line

\includegraphics{figure3.png}

It shows the image that I want to put into the document, so I know that it knows that the image exists.

Another thing, I copied and pasted code that worked from another file("document") and used the other file "atom", but now that doesn't work anymore either, so something obviously changed.

Any help would be appreciated, I'm pretty desperate at this point.

What you posted here is obviously not your document because it doesn't have \documentclass, etc. so there is no way that can work. You have to include the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers. See minimal working example (MWE). — Henri Menke, Dec 14 '19 at 06:11
Thank you, I'll edit my post and put that in, like I said, I'm new, so I'll take any corrections :) — astrocat1701, Dec 14 '19 at 06:15
Welcome to TeX.SE... What command you execute to run the TeX file? If you are using PDF or JPG or PNG images, then you should run PDFLaTeX, or XELaTeX or LuaLaTeX, etc... — MadyYuvi, Dec 14 '19 at 06:18
Do you have any invisible nonstandard characters in your document? You can check e.g. at https://pteo.paranoiaworks.mobi/diacriticsremover/. If this is not the case, could you perhaps show the log file? — , Dec 14 '19 at 06:28
Just wondering, why are the files you are working on under program files and not say your normal documents? Also please post the full log of wha you get when you compile this particular mwe (the contents of the generated log file not the "log" texstudio shows you) — daleif, Dec 14 '19 at 06:37
I think I put them there because I assumed they had to be with the program in order to run, but I guess I can probably move them (if it won't mess anything up) and the errors that are produced are just this "line 6: Undefined control sequence. \includegraphics{figure3.png}" like 5 times and then "line 6: File `figure3.png' not found. \includegraphics{figure3.png}" — astrocat1701, Dec 14 '19 at 06:50
I'm not interested in the error lines, the whole log file, it may contain more relevant information about your issue, information that might have been filtered away by your editor, which is why I explicitly ask for the full file. You can open the log file in texstudio and then update your question with the contents of the log file (like you did with the mwe). Btw when you answer a specific person use @name, then they get notified about your answer — daleif, Dec 14 '19 at 07:02
Under normal circumstances running latex on a file explicitly generates a separate log file. Interestingly I don't see one in your image. Also for that mwe it should not be more than perhaps 20 lines. For fun could you run pdflatex on that file using the dos prompt or what ever it is called these days just to see if that makes a difference, also copy the files away from program files, those folders may have special security settings in Windows (though yours are under the d drive so I'm not sure it applies. You could make a temp folder on c or d and put it there — daleif, Dec 14 '19 at 07:10
@daleif I'm not familiar with using the dos prompt, how would I run that? — astrocat1701, Dec 14 '19 at 07:14
The log file is relevant. Please fully update you miktex in both miktex user mode and miktex admin mode. There are several things related to oberdiek that has changed and miktex is notoriously itchy about some of these changes especially if you do not update both miktex branches. Note that the real error is Undefined control sequence. \Ginclude@graphics ...e \expandafter {@curr@file }}\expandafter \filename@p... l.6 \includegraphics{figure3.png} (see why I wanted the real log not the fimtered which is wrong) — daleif, Dec 14 '19 at 07:20
may the link https://tex.stackexchange.com/questions/511138/miktex-graphics-version-1-3b-bug-on-windows-10-setcurrfile-undefined helps you...but not sure... — MadyYuvi, Dec 14 '19 at 07:23
@daleif so I just went in to update my miktex and that was the update that was there, and it fixed my issue, and the image is popping up in the document now, so thank you so so much for suggesting that — astrocat1701, Dec 14 '19 at 07:26
And you are one of many miktex users with a similar problem. With miktex always update in both modes. Personally I do not use miktex and thus does not get this issue. — daleif, Dec 14 '19 at 07:28
@astrocat1701 From todays point of view, you did mostly everything correct. Congratulations. The only comment I have, that there is no need, to add the image file name extension. Writing \includegraphics{figure3} should be sufficient. As you can see in you logfile, LaTeX will automatically try .pdf,.png,.jpg,.mps,.jpeg,.jbig2,.jb2,.PDF,.PNG,.JPG,.JPEG,.JBIG2,.JB2,.eps. As long, as your file uses one of this extensions, you are fine. — Jan, Dec 14 '19 at 08:03
And one other hint (not relevant to your example): when your image is not in the directory as your LaTeX file, you have to add a path, where to find it. On a Windows-System, this might be something like C:\Users\astrocat\images\figure4. Unfortunately, MS uses the same backslash, that TeX uses as introduction for a command. Hence you have to convert the backslashes into normal slashes: C:/\Users/astrocat/images/figure4! Be aware of spaces in the path- or filenames! LaTeX doesn't like them at all! — Jan, Dec 14 '19 at 08:08

Your miktex is not correctly updated.

Make sure to update your miktex in both miktex 6ser mode and in miktex admin mode (not related to Windows admin)

Several latex bundles are currently being reorganised and miktex often has issues with these reorganisations, so remember to always update miktex correctly.
