I booted the kernel 5.13.12 with the dock unplugged, everything went well. Once the dock was plugged in, the screen froze but strangely this time, I could move the mouse on the screen (with the trackpad of the laptop). Maybe I didn't notice this possibility before?
I then started the kernel 5.14.rc3 and everything worked fine, even with the dock plugged in.
