Im using Windows 10 pro, and I installed both MikTeX (basic-miktex-22.3-x64) and Texmaker (Texmaker_5.1.3_Win_x64). When I try to build any .tex file in Texmaker it gives me the error:

pdflatex -synctex=1 -interaction=nonstopmode %.tex

Process started Sorry, but pdflatex did not succeed. The log file hopefully contains the information to get MiKTeX going again: C:\Users\YesabethGB\AppData\Local\MiKTeX\miktex\log\pdflatex.log Process exited with error(s)

The log says this:

When I searched for a solution most of what I read said that it was an installation related problem in which the formats were not build and the solution for most people was to reinstall MikTeX. So I uninstalled both MikTeX and Texmaker using IObit Uninstaller, then I rebooted the PC and reinstalled both programs, same thing happened.

Then I tried to build them manually in the MikTeX console (all of the formats appeared either blank or excluded in the attributes section of the menu), then this error appeared:

One MiKTeX Utility failed for some reason. The output has been saved to a file.

I looked into the makefmt folder and there was this log:

    I have seen this error a few times. In one case the unicode-data package simply wasn't installed tex.stackexchange.com/a/344493/2388., but there are also cases where it is unknown what triggers it. github.com/MiKTeX/miktex/issues/901. Install texlive 2022 if you don't get miktex working. May 30 at 19:00
  • You should launch MikTeX Settings, click on the formats tab and select the formats you want to build.
