After upgrading vs2019, and then also after installing vs2020 I can't open C# projects. Whenever I try to open I get first error boxes notifying that VS is not able to load the RoselynPackage and the CSharpPackage, and after that in output I get error message like this project 'Assembly-CSharp' could not be opened because the Visual C# 2022 language service could not be created. Value does not fall within the expected range.
Tried suggested method to delete \AppData\Local\Microsoft\VisualStudio\17.0_064520ec\ComponentModelCache and cleaning nuget etc (How can I fix the Microsoft Visual Studio error: "package did not load correctly"?) cache but nothing seems to help.
Also tried what is suggested here Error HRESULT E_FAIL has been returned from a call to a COM component VS2012 when debugging
Tried to repair. Tried to clean visual studio and reinstall, did not help either.
Found that if I create a new account on Windows and open visual studio from there, it works fine. Only in my account does it not work. Registry issue?
This is what I get in activity log.
