Trados 2024 - Error when opening project with locked segments

Question

Good morning, 
 I need urgent assistance with a serious issue. 
 I recently upgraded from Trados Studio 2022 to Trados Studio 2024 (Trados Studio 2024 SR1 - 18.1.2.6370) . The installation completed without errors, and I reopened the projects that were previously listed in the 2022 Projects view. 
 However, when I open any project that contains locked segments , I immediately receive the following error:

If I click OK and close the error message, all toolbar buttons (and other interface buttons) become disabled, making it impossible to work on the file: 
 
 Projects that contain only unlocked segments open and function normally. 
 
 Troubleshooting steps already tried (without success): 
 
 Recreated the project from scratch in Trados 2024 
 Attempted to unlock segments (option is disabled) 
 Ran Trados Repair 
 Uninstalled the following plugins: Integrated Segment Actions, Segment Status Switcher, SegmentSearcher

This issue is blocking my work completely. I urgently need to know: 
 
 How to resolve this problem in Trados 2024 
 If it is possible to revert back to Trados 2022 in the meantime 
 
 Thank you in advance for your help.

 Hello Lara, 
 I understand that you're facing a significant issue with locked segments in Trados Studio 2024. Let's work through this step by step to find a resolution. 
 **Step 1:** Ensure that Trados Studio 2024 is fully updated. Check for any available updates within the application. 
 **Step 2:** Since you mentioned that the error occurs specifically with projects containing locked segments, try the following workaround: 
 - Close Trados Studio completely. 
 - Navigate to the folder: `C:\Users\%username%\App Data\Roaming\Trados\Trados Studio\18` (make sure hidden items are visible). 
 - Rename the `Studio18` folder to `Studio18_old`. This will reset your settings and may resolve the issue. 
 **Step 3:** If the problem persists, consider running a repair installation of Trados Studio 2024: 
 - Go to Control Panel > Programs and Features. 
 - Find Trados Studio 2024, right-click on it, and select "Repair". 
 **Step 4:** If you still encounter issues, you may want to revert to Trados Studio 2022 temporarily. To do this: 
 1. Close Trados Studio 2024. 
 2. Uninstall Trados Studio 2024 from your system. 
 3. Download the installer for Trados Studio 2022 (version 17.0.0.11594) from the Knowledge Base. 
 4. Install Trados Studio 2022 and check if your projects open without issues. 
 **Step 5:** If you are able to open projects in Trados Studio 2022, you can continue your work there while waiting for a fix for the issue in Trados Studio 2024. 
 If none of these steps resolve the issue, please provide the exact error message you are receiving, as well as any relevant logs or screenshots, so we can further assist you.
