Crash on saving an autocreated testplan in Xcode 16.3?

Is anybody able to save the autocreated testplan successfully with Xcode 16.3? I get a crash no matter what (different filenames, locations, machines, ...). Now created a template project: same thing.

Xcode Version 16.3 (16E140) on macOS 15.5 (24F74)

Known issue, or am I holding it wrong?

Same result with Xcode 16.4 RC. With a template project the save fails silently.
