LLDB fails to launch app from XCode 12

We are updating our macOS projects for Universal binaries and our two main apps fail to debug in Xcode 12.2 (on Big Sur), but I can use lldb from the command line to run the built app.

When I try to run the app in the debugger in Xcode I get this error:


Warning: Error creating LLDB target at path 'my app path'- using an empty LLDB target which can cause slow memory reads from remote devices.
error: failed to launch '2687' -- LLDB provided no error string



I assume the number is the PID, it changes each time I try to run the debugger. Not sure what to do.
If you create a new test app from one of the built-in templates, does that also exhibit the problem?

I started getting lldb provided no error string right after I installed Big Sur beta last week.
