[BUG] Win32Exception (2): An error occurred trying to start process

[jhm-ciberman]

I'm trying to unintall "phantom" installations of DotNet that I cannot even remove from the Windows 11 "Installed Apps" page on the Settings app. But it seems not even the official dotnet uninstall tool can uninstall them:

I wanted to uninstall everything to be able to install just the latest SDK.

PS C:\Users\jhmci> dotnet-core-uninstall remove --all --sdk
The following items will be removed:
  Microsoft .NET SDK 6.0.318 (x64)

To avoid breaking Visual Studio or other problems, read https://aka.ms/dotnet-core-uninstall-docs.

Do you want to continue? [y/n] y
