minas.pngwith a file that exists on my system and compile your code withxelatex, I do not get any error. Which compiler do you use? In order to debug the error, you may remove all but the necessary packages, and then see what happens. – Feb 09 '19 at 22:11txfontsormulticolto show the error, delete every packag ethat you can delete to make it easier to debug. but as I say show the log file which will show which file is in error., – David Carlisle Feb 09 '19 at 22:15
