I got it to work with first Xcode 13 beta 1 / Mac OS 12.0 Beta 1. Just updated to latest Xcode beta and I get same error as you. :-( It was pretty cool what it could do. I would run the HelloPhotogrammetry executable I made already but somehow the OS thinks it is malware cause it has an old cert... So I have to rebuild.

This bug has resulted in daily headaches on an 8GB M1 to the point of making it unusable to run anything else simultaneously. I understand the Apple yearly release, but it is absurd that this bug, clearly clearly a reproduce-able bug, has simply been something we are expected to deal with, for a year. C'mon make a hot-fix when your stuff is sooooooo broken. I stopped using Safari completely, except, you know all my passwords, bookmarks and auto-fill data are there, plus airplay only works from there.... So it's open all day anyway. Get it together please.
