Disabling addin doesnt helped.

Hi,

Based on the description, it seems the error occurs when you start Word with a 3rd-party add-in.

Please try to start Word in Safe Mode first, check if the issue persists without the add-in:

Press Win + R, type "winword.exe /safe" in the blank box.

If Word runs fine in Safe Mode, we may suspect the add-in itself is damaged, we can try to re-install the add-in.

If the issue persists, since the add-ins is not a Microsoft product, we need to contact the developer of this add-in for further assistance.
