Error "Object reference not set to an instance of an object" when trying to change the TM User ID in File -> Options -> Translation Memory Updates -> TM User ID

Hi,

I couldn't find any topic on this problem: when trying to change the TM User ID in File -> Options -> Translation Memory Updates -> TM User ID the "Object reference not set to an instance of an object" is displayed. I was able to change the ID within a project in the project settings, however, when updating a segment the "old" TM User ID is still used. Thus I wanted to check the ID on the higher level but can't even open the respective window. I am using SDL Trados Studio 2019 SR2.

Thanks for any help!

Best wishes,

Heike
