@ErikSharp I found some workarounds that resolved the issue for me, more specifically:

• this workaround involving uninstalling the build tools
• Or this workaround to rename the MSBuild directory there

Unfortunately, the issue doesn’t seem to be considered serious here as none of the maintainers has commented on this.

@akshita31 Will the root cause be fixed? After all, a workaround should not be considered as the solution. I do need the Build Tools for building other things like C++.
