Hello,  

It sounds like you're experiencing a frustrating issue with Trados Studio 2022. The error message "Failed to add window command bar extensions" can be caused by various factors, but here are some steps you can take to troubleshoot and potentially resolve the issue:  

**Step 1:** Close Trados Studio completely.  

**Step 2:** Navigate to the following folder:  

`C:\Users\%USERNAME%\App Data\Roaming\Trados\Platform\Identity`  

If you can't find the path, make sure to enable "Hidden Items" in Windows File Explorer.  

**Step 3:** Rename the folder `SDLTrados Studio.exe` to `SDLTrados Studio.exe-old`.  

**Step 4:** Restart Trados Studio and check if the issue persists.  

If the problem continues, you can also try the following additional steps:  

**Step 5:** Check for any pending Windows updates and install them. Restart your computer after the updates are installed.  

**Step 6:** If you have any plugins installed, consider removing them temporarily. Navigate to:  

`C:\Users\%username%\App Data\Roaming\Trados\Trados Studio\17\Plugins\Packages`  

Delete any plugins you suspect might be causing the issue, such as `Language Weaver Cloud.sdlplugin`.  

**Step 7:** If none of the above steps work, consider performing a repair installation of Trados Studio. You can do this by going to Control Panel > Programs and Features, selecting Trados Studio, and choosing the Repair option.  

If the issue still persists after trying these steps, please provide any additional details about your setup, such as the exact version of Trados Studio 2022 you are using and any other troubleshooting steps you've already attempted.
