Can't start neither Trados Studio 2021 nor 2022 - unable to work!

I use Trados Studio 2021 and recently I purchased upgrade to Trados Studio 2022 from my 2017 version. I installed Studio 2022 on the same computer where I have 2021 version installed. Just after 2022 installation, 2021 stopped working. During initialization there is a flash display of some window or two and process stops without starting the program (2021). Windows pop-up so quickly that I can't read them. I run repair installation. No effect. I uninstall and re-install 2021. No effect. The same.

Fortunately, I still was able to use 2022 freshly installed. Unfortunately very shortly, until I decided to install a few plugins, not from within Studio 2022 but downloading plugins from RWS AppStore. Now when starting 2022 I have a message:

"Sdl.TranslationStudio.AlignmentEditor.IAlignmentEditorService' could not be started."

and

"Element o tym samym kluczu został już dodany."
