Windows 11 Canary channel serious crashes

[North_Yang]

My laptop running the newest Canary version crashed many times today when I was using high-performance needed applications.

My accounts got log out. It even has some problem to log in to windows, is there any way to solve it？

In this menu you may press Shift key and restart and boot into Safe Mode to see if you are able to login?
