Hi @Niraj Bothe ,
Welcome to Microsoft Q&A!
Please close all running VS instances and rename (or delete) every ComponentModelCache folders under this path: C:\Users[username]\AppData\Local\Microsoft\VisualStudio\17.0_XXXXX. Then, re-run VS as administrator.
If you are using the latest version of VS2022, I suspect it is a known issue.
You can try to run the following command in an elevated command prompt:
gacutil /if "<vsinstalldir>\Common7\IDE\PublicAssemblies\System.ValueTuple.dll"
If it doesn’t work, you can vote and add your comment at the ticket:
RoslynPackage fails to initialize due to SettingsEditorFactory dependency error - Developer Community (visualstudio.com)
Please kindly wait for a fix to be released.
