Impossible start Trados Studio, even worse after trying repairing!

I'm in despair about the new problems with Trados Studio 2022. I needed to update a TM and downloaded the "Trados Compatibility and Migration Power Pack" as you suggested. Trados crashed and impossible to restart: Error "Sdl.Desktop.Platform.CommandBars.IActionService could not be started" when starting Trados Studio. I spent hours following your instructions for repairing and restarting TS. No success, I am afraid I lost my work and my TM...Please contact me ASAP to help.
