"Windows must always have a parent" crash

[nikitabobko]

I still experience occasional crashes, about once a week, when opening an Xcode project from the command line using the command: open "project-name.xcworkspace".

I've encounted the same problem: "Windows always have parent" occasionally after upgrading to 0.18. Haven't found any way to reproduce it.

After it crashes, I have to restart the OS to make aerospace working again

same here

I am also getting this (and other crashes) multiple times per day starting with the most recent beta. It's often when moving a window from one workspace to another, or even when changing workspaces, but sometimes it's just when focusing on another window. Happy to provide any info/help I can (love this project!).

[kyeb]

Adding another sample, in case a datapoint helps. I haven't figured out what's triggering it yet, but it has happened twice. I also land in a state where Aerospace is totally frozen and broken, and I have to kill it with either Activity Monitor or killall to start over.

Having this crash too while switching between spaces. Might have something to do with PiP.

[acsandmann]

some info that might help is that I primarily encounter the issue when quitting an app with cmd+q. I think AeroSpace might be trying to get info from the window as it closes but since the app is also closed it has no "parent".

[lalitaalaalitah]

Hi,
Same here. It happens when I close all windows of an app with cmd+q.

If it happens then I've to kill all processes related to aerospace in Activity Monitor and then launch aerospace. Without this it never works.
