I have TexStudio and MikTex to edit Latex files on my PC. After updating both of them to the versions 4.0.3 and 4.4, respectively, the compilation started to show a lot of errors on the memoir.cls file:
When I try to compile a simpler file that doesn't use memoir.cls it works fine. I've already tried downgrade and reinstalling both.
Minimal Reproducible Example
\documentclass[msc]{ppgccufmg}
\begin{document}
\end{document}
Class ppgccufmg: https://github.com/verlab/ppgccufmg
If you want me to send anything else to help diagnose just let me know.
