Blank Chat Archive

I went to go create a backup of our chat archive, but was met with a blank, textured page with a 'Hide Whispers' button that did not do anything. Upon further inspection, it seems the cause may be a JSON error. I have followed the Technical Issue guide, and still no luck. Is there a way this can be restored so we can make a backup of our chat archive before clearing it?

We figured something like that was the cause! We have a new rule not to paste from PDF anymore, so hopefully it's avoided in the future. If you could please remove the offending session so we can get a backup, that would be great. Thank you!
