Studio 2021 crashes when I add a term to Multiterm. But not always--only about every third time I add a term. 

I have already tried to insert the exception for the antivirus program as described in this post. https://community.rws.com/product-groups/trados-portfolio/f/licensing/36545/tm--versucht-geschutzten-speicher-zu-lesen-oder-zu-schreiben-dies-ist-oft-ein-hinweis-darauf-dass-anderer-speicher-beschadigt-ist.

Logfile: 

ERROR [2022-01-04 11:49:12,450] Sdl.TranslationStudio.LanguageCloud.Services.LanguageCloudProjectMigration - Der angegebene Schlüssel war nicht im Wörterbuch angegeben.
System.Collections.Generic.KeyNotFoundException: Der angegebene Schlüssel war nicht im Wörterbuch angegeben.
   bei System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   bei Sdl.TranslationStudio.LanguageCloud.Services.LanguageCloudProjectMigration.CheckProjectsForMigration()

What does this log mean?

I am not sure if this log points to the crash.

I have read in the forum that this problem already exists since Studio 2015 and unfortunately I have not found a clear solution to this problem.


How could one eliminate the crashing?

Thanks

Best Regards
