Visual Studio 2019 has stopped working after update 16.9 was installed. I get errors such as "package did not load correctly". Does anyone else have this issue? I did tried many things such as re-installing but no matter what I did the issue still remains.

    When I run Visual Studio as administrator it works. When I run as a normal user error displayed in popup "The 'Environment Package Window Manager' package did not load correctly" and Visual Studio fails to open.

    I have the same issue, and deleting the %localappdata%\Microsoft\VisualStudio\16.0_xxxx\ComponentModelCache folder doesn't help. Running as administrator does.
