I have Studio 2021, no issues ever. I tried to install the Juremy plugin, which did not work. I then thought I'd install service pack 2, as I had never installed it. After that, error message:
Service 'Sdl.Desktop.Platform.CommandBars.IActionService' could not be started
I tried to repair, uninstall, even a system recovery (the latter did not work due to other programs, Dropbox) so a systemrestore is not possible. Everything mentioned in the support articles.
Not sure what to do now - as I have a deadline to meet.
