If you get the Easy Anti-Cheat Untrusted system file error for Example:
C:\Windows\System32\vcruntime140.dll
C:\Windows\System32\msvcp140.dll
then head over to your installed apps, filter for "visual" to only see the Microsoft Visual C++ Redistributables and REMOVE (uninstall) all of them with year 2015 and later.
After that, head over to Microsoft https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170 (Microsoft Visual C++ Redistributable latest supported downloads)
Download and install the X64 Version (or also the X86 Version to be safe or if you don't know which one is correct for you). After installation a system restart is necessary.
Now the Error should be gone.
I had the error after updating my Microsoft Visual C++ Redistributables via WinGet, if you use it too, make sure to ignore these updates in the future.
