I own Trados Studio last version 2021 SR2 and Windows 10.

I have a problem with Trados: each time I try to open the files for translation I get different errors, one error with one file, another with another file.

ErrorMessage>The requested service is not available: Sdl.TranslationStudio.Api.ProjectManagement.IFilesViewService.</

ErrorMessage>Unexpected exception when initializing view part Fragment Matches

I have already tried: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0034055

And: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0033669

Nothing works and I am desperate with several files to translate.

This started in October, I uninstalled, I downloaded again, nothing works. 

Can you help me?

Thank you.
