I think the first thing would be for you to do a full reinstall and reset.  So please close Studio and then do the following.

Delete this folder:

c:\Users\%username%\AppData\Roaming\Trados\Trados Studio

Then run a repair installation through your windows control panel.  To do this press the Windows key + R then type: appwiz. cpl and hit the Enter key.  This should open the add/remove programs dialog in your windows control panel.

Look for Trados Studio 2022 and click on Uninstall/Change:

yes to the question about uninstalling/changing and then select repair at the next prompt:

Once repaired restart Trados Studio and see if the situation improved.

You will not lose any of your translation projects with this process, but you will get a clean install.  It's also worth making sure you have the latest update so look out in the top right hand corner of Studio once it starts for a notification as we released CU4 on Monday.  If it's there click on it and follow the instructions to download and install.

Thank you very much for your answer.

Unfortunately nothing worked. I'm starting to run out of options... 

I am having the exact same problem here. Deleting the folder and reparing does not help, neither does doing a complete desinstall and reinstall. I just cannot see what else I can try.

Hello Léo, I'm having the same issue here and nothing works. How did you finally fix it? I could really use some help right now!

Hi Ines. On my side, the problem solved itself after a Windows update. I was told by Support that I would need to reinstall Windows because some files were corrupted, but apparently the Windows update took care of it.

Thanks a lot, C Boucher! Running the latest Windows update also solved the problem automatically for me. You saved my day!!!

Glad to know it worked!
