Has anyone seen this Rosetta error during debugging in Xcode?

Recently, I've seen this error come up during debugging a MacOS Intel build on an M1 Pro in Xcode

13.4.1 (on Monterey 12.6.7):

rosetta error: unable to get state for thread the runtime suspended

Then the app crashes (debugger shut down first):

Big, long, complex, mature application. This is happening after I've made some calls to the NSBookmark creation / resolution API, then crashing downstream after issuing a menu command. Any clue as to what this means, or how to determine why it's happening?
