Feedback crash every time the window gets activated

This has happened for quite some time now. On Windows 10 64-bit, every time I switch to the Feedback window Feedback opens the “Error Detected” window - “Feedback has detected an error in %1. Please tell us…” Clicking submit gives me the unexpected error and the application then closes.
If I click “Discard” I can continue using the application normally but the same error pops up again if I switch to another application and then back to Feedback. Annoying…
