In the meantime, based on the information you have provided, here is a suggested answer to your question:

Hello,

The error message you're encountering usually occurs when the software tries to access an element from a collection that doesn't exist. This could be due to a variety of reasons, including corrupted files or issues with the software itself.

Here are some steps you can try to resolve this issue:

Step 1: Close all running instances of Trados Studio.

Step 2: Navigate to the following path: C:\Users\%USERNAME%\AppData\Roaming\Trados\Trados Studio\

Step 3: Look for the folder named 'Studio17'. If you can't find it, make sure that hidden files and folders are shown in your Windows settings.

Step 4: Rename the 'Studio17' folder. This will reset the basic settings of Trados Studio.

Step 5: Restart Trados Studio and try to verify your document again.

If the issue persists, you might need to reinstall Trados Studio. Please ensure to back up any important data before doing so.
