I'm having exactly the same issue: my app worked under Rosetta2 when still running Big Sur beta, but after upgrading to the official Big Sur release, the app doesn't start anymore and has the "no sign" in the icon. Command line:

% open MyApp.app 
The application cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10661 "(null)" UserInfo={_LSLine=3665, _LSFunction=_LSOpenStuffCallLocal}

I can repro this, I'm assuming though that this is specific to the DTK and will not occur on M1 machines. I'm just checking up on this though, will see what I find.

Confirmed that this will work just fine on the M1 machines. If you want to workaround this on your DTK ensure you launch the app from terminal directly. E.g.

./MyApp.app/Contents/MacOS/MyApp

Thanks @MarshallOfSound! I can confirm that the workaround works in DTK.

I updated to 11.0.3 and now the app works again normally. This was included in 11.0.2: #26570, might be related.
