I think the driver for the MCS board is facing the same issue. I'm not sure if this is a bug in the new Raspberry Pi kernel or a feature. The problem is definitely caused by a fixed device numbering for TTY devices.

Again, when restarted today, the HAT is blocked ... luckily everything is still on the desk!
You need to give more details otherwise it might be difficult to get the issue solved.
Have you changed your system configuration? Is only the HAT installed or other hardware as well?
It would be very unusual if the driver suddenly stopped working.
Please provide the output of dmesg.
No, I haven't changed anything. The same problem is reproduced:
