Form not opening, showing error "Sorry, something went wrong"

[s_imfeld]

I created a Microsoft Form as a group form. At first everything was fine, but now when I try to edit it doesn't load an displays the error "Sorry, something went wrong" with a session ID.

Only a single form is affected, all the other forms work well. All members of the team fail to open this specific form.

Update: Mysteriously it seems to be working again, although I didn't change any settings or whatsoever. Which doesn't change the fact that I could not work on the form for more than a week.
