Hello,  

It seems you're encountering a persistent error when trying to launch Trados Studio 2022 due to the "Unexpected error while loading application plugins." Here are some steps you can follow to troubleshoot and potentially resolve this issue:

**Step 1:** Close all RWS applications completely.

**Step 2:** Navigate to the following directories and rename or delete the `Plugins` folder:

- For Trados Studio 2022:  

 `C:\Users\%USERNAME%\AppData\Roaming\Trados\Trados Studio\17\Plugins`  

- For Local folder:  

 `C:\Users\%USERNAME%\AppData\Local\Trados\Trados Studio\17\Plugins`  

- For Program Data:  

 `C:\ProgramData\Trados\Trados Studio\17\Plugins`  

**Step 3:** After renaming or deleting the `Plugins` folder, you may also want to check for any remaining third-party plugins in the `Packages` and `Unpacked` folders and remove them.

**Step 4:** Run a repair installation of Trados Studio. To do this, go to Control Panel > Programs and Features, find Trados Studio 2022, right-click on it, and select "Repair."

**Step 5:** Restart your computer and then try to open Trados Studio again.

**Step 6:** If the issue persists, consider reinstalling the plugins you need from the integrated AppStore in Trados Studio, ensuring they are compatible with your version.
