Development distribution - "App" is damaged and can't be opened...

XCode 11.4, macOS 10.15.4. When launching development distributions, I am now getting the error: “AppName” is damaged and can’t be opened. Delete “AppName” and download it again from the App Store. If I relaunch once or twice, I will eventually get the login prompt, and after I enter testing credentials, it launches fine. Anyone else experiencing this?

I don’t do a lot of Mac App Store stuff but the last time I saw this problem it was triggered by code in the app calling

exit
with a status 173. Are you sure that’s not the case here?

Getting that error is not unusual. I've never seen it work after I keep trying. What I have to do is bump the build number and generate a new archive.
