This morning I was notified of an update for trados studio 2024 through the notification tab (bell icon).

I got the update, and after I am constantly facing all kinds of error pop ups when working on my project. (which was doing fine 40 mins ago)

After some troubleshooting and multiple attempts at reinstalling both multiterm and trados studio 2024 sr1, I was able to get rid of some but not all problems. 

Current version : Trados Studio 2024 SR1 - 18.1.2.6370

I have 2 main problems left : 

1. [project settings] not working

From time to time I cannot access the [project settings] button, when I click it, the pop up says : Object reference not set to an instance of an object.

Oddly this error happens 50% of the time, and sometimes it works fine without any errors.

After that, I try to [use] a termbase (since the one I was using was suddenly unusable, I took it off the list - so there's none right now)

again, an error :

So currently I have been unable to work.

Is there any way of fixing this? 

(TM is perfectly fine, and the TB is working fine on Multiterm)

 

So far I have tried :

- renaming the trados studio file

- renaming the html files in the trados studio files (basesettings, usersettings, plugincache)

- restarting the computer

- reinstalling (using the windows control panel)

- reinstalling ( downloading this : - Trados Studio and Multiterm download installers for each cumulative update - RWS Customer Support )

Thank you in advance.
