[Qt-creator] Unable to debug with latest XCode

[Jason H]

I upgraded my XCode to 11 (it goes to 11!) (Qt calls it "SDK 10.15") and I can't debug.
All it says is:
09:39:23: Debugging starts
the debug panes pop up, empty, and it just sits there. I can't kill it by the usual means (no red square, attached), but I can kill it by closing the output pane. At which time I get two popups (attached)

Has anyone else seen this with XC11? Known issue, or should I report it in Jira
