Visual Studio 2017 freezes on startup. Activity log shows error

I came in to work today and cannot launch my Visual Studio 2017.

ActivityLog shows

Construction of frame content failed. Frame identifier: ST:0:0:{007a3a6b-b5b2-454d-a2bd-cf929f989be2} Frame caption: Exception details: System.UnauthorizedAccessException: Access is denied.

Appid denied the loading of package

Package failed to load; error message suppressed by skip flag

I don't even have to open a solution and it still hangs. Tried devenv /resetsettings, devenv /safemode, none of them worked.
