Hi Dan Flagg ,  I responded to a similar issue a few days ago.

I'll add my response here again. Let me know how it goes.

Possible Cause:

This error typically occurs due to corrupted user settings or configuration files within Trados Studio. Resetting these files often resolves the issue.

Here are some options you can follow to fix the problem

Option 1: Reset Trados Studio to Default Settings

Step 1: Close Trados Studio

• Ensure that Trados Studio is completely closed before proceeding.

Step 2: Rename the Settings Folder

Navigate to the Settings Folder:

• Press `Windows Key + R` to open the Run dialog.
• Type `%appdata%\Trados\Trados Studio\Studio18` and press `Enter`.

Rename the Folder:

• Find the file named `UserSettings.xml` and rename it to `UserSettings_old.xml`.
• Alternatively, you can rename the entire `Studio18` folder to `Studio18_old`.

Step 3: Restart Trados Studio

• Launch Trados Studio.
• The application will create a new settings folder with default values.
• Check if the application starts without the error.

Option 2: Delete the FilesView Configuration File

Step 1: Close Trados Studio

• Make sure Trados Studio is not running.

Step 2: Navigate to the Local App Data Folder

• Press `Windows Key + R` to open the Run dialog.
• Type `%appdata%\Trados\Trados Studio\Studio18` and press `Enter`.

Step 3: Delete the Layout Configuration Files

• Look for files related to layout and views, such as `BaseSettings.xml`, `Plugincache.xml`, or specifically any file that references `FilesView`.
• Caution: Deleting these files will reset your layout customizations.

Step 4: Restart Trados Studio

• Open Trados Studio to see if the issue is resolved.

Option 3: Repair or Reinstall Trados Studio

Step 1: Repair Installation

• Access Programs and Features:
• Go to `Control Panel` > `Programs` > `Programs and Features`.

• Follow the on-screen instructions to complete the repair process.

Step 2: Restart Your Computer

• After the repair is complete, restart your computer.

Step 3: Launch Trados Studio

• Open the application to see if the issue has been resolved.

Option 4: Check for Conflicting Plugins or Add-ons

Sometimes, third-party plugins or add-ons can cause conflicts.

Step 1: Close Trados Studio

• Make sure Trados Studio is not running.

Step 2: Disable Plugins

• Navigate to the Trados Studio plugins folder:
•  `%appdata%\Trados\Trados Studio\18\Plugins`
• Temporarily move any third-party plugin files to another location.

Step 3: Restart Trados Studio
