I'm not sure if it was changed recently in VS, it seems to me that i have used previous versions without such problems. But with VS 19.2 it tries to convert projects for no reason and ends up with broken project files.
It seems including common.targets doesn't work as expected. I have fixed projects manually, but the long term solution seems to switch to Directory.Build.props and Directory.Build.targets.
