@lifeofguenter I can't reproduce this myself, but I have seen other reports of this. I'm still not sure what's causing it.

Is there a crash message? Do you have any kind of window management software? Is there another machine you can reproduce this on? Is the window hidden at all?

Unfortunately I do not know how to reproduce. I had to uninstall app and re-install from AppStore. So seems like some local file within the .app got damaged/changed/bricked?

No hidden window via “show all windows”.

@lifeofguenter Is it fixed now that you've reinstalled?

*I have isolated the issue to be related to external monitor. I have my own app that is having the issue but also I am not able to reproduce it.

Is this still an issue for anyone on v5.9?

I'm seeing the same issue with 5.10.1 on my M2 Max MBP running Sequoia 15.2 (I've seen it under previous releases as well). I have multiple monitors and MM was on my non-primary monitor.

If I reboot the Mac I can usually get the window back...

I don't know what steps to take to reliably reproduce it, but it happens fairly regularly.
