I spent some time the identify which kernel version it started failing and found it started from -1058.

The usb stick only can be detected after re-plugging it to the machine.
[Additional information]
Affected machine:

Previously we always use its type-a port for testing, but recently we connected a zapper to it, occupied 2 type-a port, so moved the usb stick to type-c port, that's how I found the issue.
I attached 3 journal logs
1057.log: the journal with -1057 kernel
switch_1058.log: the journal log that the first boot from -1058, in this log, the usb stick(/dev/sdb) still can be detected
reboot_1058.log: the journal log that do the reboot when stay at -1058, you can see the /dev/sdb disappear.
