Trados Studio 2021 keeps crashing

Hi,

I have Trados Studio 2021 since last year, and use Trados since 2014. This is the first time I have such a problem. Trados keeps closing down suddenly while I am working. I have tried the two issues:

Installation repair: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0039395

Reset to default settings: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0033669

But the problem continues.

I really don't know what to do, hope you can help me, Kind regards
