"Content failed to load" on Edit GPT

Trying to edit one of my GPT and getting “Content failed to load”. I can edit other of my custom GPT without problem. The GPT itself works fine, I just can edit it.

Bump. Getting this issue too and have no clue how to resolve.

Same here. I try to edit or generate a new answer, but nothing. Tried to clear all cache and cookies, log out then back in — nothing.
