I experienced a similar issue twice during the last week with
Ubuntustudio running with kernel:
5.4.0-58-lowlatency #64-Ubuntu SMP PREEMPT Wed Dec 9 09:48:08 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
The system completely freezes and I have to press the reset button.
These are the journal entries:

The problems started when I connected a ASUS WLAN stick. I unplugged it
now and check if the problem persists.
