Unable to Close UE5 when Control Rig editor is open

When the Control Rig editor is open pressing the UE5 App close button (top-right corner) or using File->Exit do not work. Closing the Control Rig editor makes them available again.

Same problem. Reproducible - this was driving me crazy the last few times I was using UE5 because i’ve only been doing Control Rig stuff.

Any control rig file thats open will cause the exit functions to not work. Closing the control rig editors will give you the ability to close the app.

Same Problem.
