Working cmake/mingw configuration stopped working. The C compiler is not able to compile a simple test program - c

Question

I write the C program using MinGW on windows 10 with Clion IDE. I had everything working and compiled successfully multiple times before. Can't link the error with any action but now cmake test in Clion fails - "Test Cmake run finished with errors" and I can't compile. Cmake error:
-- The C compiler identification is GNU 9.2.0
-- The CXX compiler identification is GNU 9.2.0
-- Check for working C compiler: C:/msys64/mingw64/bin/gcc.exe
-- Check for working C compiler: C:/msys64/mingw64/bin/gcc.exe -- broken

It fails with the following output:

Error code: 1
I don't know what caused it. One thing I did around the time it broke is turn off avast cyber capture. But now I turned off avast antivirus completely and turned off "Check apps and files" option in Defender. The latter I did when Clion popped a notification saying "Windows Defender might be interrupting build speed". I also clicked "fix" in this Clion pop-up and it added project folders to exceptions. Clion notified me of it not immediately after the error but way later.
The directory "C:/Users/karol/AppData/Local/Temp/cmake_check_environment/" mentioned in the error report doesn't exist. I tried unchecking "read-only access" of AppData/Local/temp directory but Windows keeps putting it on. Between those changes and antivirus changes, I was restarting windows many times.
The error message i get when trying to compile:

Many poeple experienced simmilar error caused by non-latin characters in path, not the case here. Also i don't suspect mingw installation as it used to work.
