Getting two blank errors in every project

[Shazwalt]

I am using Unity 20.19.2.17f1 and VS code and am getting 2 black error messages in all projects. Looking into the editor.log file I found:

-----CompilerOutput:-stdout–exitcode: -532462766–compilationhadfailure: True–outfile: Temp/UnityEngine.TestRunner.dll
-----CompilerOutput:-stderr----------

Unhandled Exception: System.BadImageFormatException: Could not load file or assembly ‘System.IO.FileSystem, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’. Format of the executable (.exe) or library (.dll) is invalid.

-----EndCompilerOutput---------------

• Finished compile Library/ScriptAssemblies/UnityEngine.TestRunner.dll

I have recently started GameDev and have no idea about any technical details.

There was a bug that caused empty error messages however it is fixed in the latest versions. Can you update to 2019.4 or 2020.1?
