Steps to reproduce:
Not exactly sure how to reproduce it because I did several actions that I can't exactly recall, and it happened so fast. It started showing signs of bug a minute before crash: generally Chromium and a Finder were in the 1st window and WeChat was opened in window 2 or 3, but it strangely only takes the left 1/2 of the window while there's nothing on the right 1/2. Then I switched windows and at some moment the crash remind popped up, and then hotkeys stopped working. Action bar kept displaying Aerospace icon though.
