BibTex Error no \bibdata command

Question

I am looking for a solution and have read a lot on the Internet, which has not helped me further.

Here is my Latex

\documentclass[a4paper, 12pt]{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage[T1]{fontenc}
\usepackage{times}
\usepackage{geometry}
\usepackage{setspace}
%\usepackage[nottoc]{tocbibind}
%\usepackage{url}
%Mathepackages
\geometry{left=4cm,right=3.5cm,top=4cm,bottom=4cm}
\usepackage{amsfonts}%mathepacket
\usepackage{amsmath}%ebenfalls mathepacket
\usepackage{graphicx}
%\setcounter{secnumdepth}{5}
\usepackage[backend=biber,style=alphabetic,]{biblatex}
\addbibresource{Literatur.bib}
%\def\UrlBreaks{\do/\do-}
\setstretch{1.5}
\begin{document}
\tableofcontents
text
\newpage
\printbibliography
\end{document}

My Literatur.bib

@Online{SchengenVisa,
  author = {SchengenVisaInfo},
  note   = {Aufgerufen am 08.09.2022},
  title  = {Informationen über das Schengen-Visum},
  url    = {https://www.schengenvisainfo.com/de/},
}

If translate with pdfLatex and then with bibTex and get the following error message.

This is BibTeX, Version 0.99d (MiKTeX 2.9.7140 64-bit) The top-level auxiliary file: Masterbericht.aux I found no \citation commands---while reading file Masterbericht.aux I found no \bibdata command---while reading file Masterbericht.aux I found no \bibstyle command---while reading file Masterbericht.aux (There were 3 error messages)

Can someone please help me?

Welcome to TeX.SX! You can also put both code snippets into one, see minimal working example with bibliography (MWEB). In your example you don't use any \cite command. And more important you use biblatex with option backend=biber. Therefore you have to use biber instead of BibTeX to compile it correctly. — dexteritas, Sep 08 '22 at 15:29
How I can use biber? I use texmaker and only know how to compile with biblatex — Reazelruss, Sep 08 '22 at 16:49
