I've run into the "value cannot be null" error for 3 different project packages sent by a client. I didn't really find the previous tickets on this issue helpful.

I've got Freelance subscription and using Trados Studio 2022. I also got Trados Studio 2021 installed as backup.

I have tried:

- Updating Trados

- Updating plug-ins

- Restarting program + restarting computer several times

- Opening the projects in Trados Studio 2021. Here, two termbases are unavailable and I can open the file, but basically do not have access to anything useful.

- Enabling/disabling termbases and TMs with various results - sometimes it opens (with object reference error), sometimes it doesn't make a difference.

- Removing termbases with no different result.

Lastly, I was re-sent one of the projects without the termbases and it could open without issue. But I am still curious as to what the issue is, because the termbases would be nice to have.

Kind regards
