The problem is solved with new Mac OS 11.0 Beta (20A5374g).

If your catalyst app has multi-window support, you may still need to kill your existing app before launching the new one.

Faced same issue after upgrading to macOS 11 Beta 6. Reported bug to Apple but meanwhile found workaround - Select Product in Xcode, select 'Show in Finder'. Launch it from Finder. Additional step, hopefully Apple will look into it.

I also had the same problem. (I say had, I guess I still do, however I have a workaround) My App had been developed as iOS / iPadOS with Mac support. All has been working great throughout macOS 11 beta builds. Until today that is, when I, as you, updated to Beta 6. Upon attempting to run for macOS target I get the same error as you have posted.

After some googling I found https://www.virusbulletin.com/uploads/pdf/conference_slides/2015/Wardle-VB2015.pdf and had a go at simply opening the app directly from the build folder. Hey presto, it opened without any problems, I even cleaned out the build folder and built it again to make sure.

This would appear to be a problem that the next version of Xcode beta should fix. Until then, unless anybody can suggest a better fix, this will have to suffice for me at least :-(

I was having this same error code upon installing a Developer ID Distributed, Auto Signed version of a catalyst app on a test machine, non M1 Chip, Mac Mini(Late 2014) with MacOS Version 12.0 Beta installed.

The solution was to close the previously installed version of the app. Before opening the new version that I Airdrop over to the test Mac machine.
