0.18.0 unbound TreeNode crash

[nikitabobko]

Hey! Firstly, thanks for creating such a kickass project. I previously used macOS custom keybinds to switch between numbered workspaces, but hated the default transition as well as the lack of flexibility. v0.18.x looks like a very exciting release, and I'm sure a lot of hard work has gone into it!

I wish I could give more details as to what I'm doing to trigger this, but I have absolutely no idea. It seems to just crash while I'm working in JetBrains IntelliJ IDEA Ultimate.

Edit: I've updated to v0.18.1-beta, hoping that may help.

Edit: Seems that v0.18.1-beta causes the wallpaper to pop up whenever switching spaces. Guess I'll try downgrading to v0.17.1.

Hi, I'm seeing similar crashes when triggering/untriggering the Superwhisper app. I also see the same message about the "AppBundle.MacWindow is already unbound".
I did not experience such crashes on v0.17.1 but I'm triggering it quite frequently on v0.18.0 and v0.18.1.

[nikitabobko]

Should be fixed in 0.18.2. Please let me know if it's not

[wolveix]

Thanks @nikitabobko, I've just updated and will let you know! I mentioned at the top (in my edit) that the wallpaper seems to flash now when switching between spaces -- is this a known issue?
