xapp-sn-watcher crashes while booting if notebook boots without power cable

[jdepi]

Dear all,
I have a very new HP Laptop 15s eq0 with bios from april, 2020 and a Ryzen 5 3500U inside.
I installed LinuxMint 20 and everything looks fine, Mint is installed and customized, kernel 5.4.0-39-generic x86_64 is running, but:
if I disconnect the power cable and boot the laptop I will get a black screen instead of a login screen. After waiting a minute I powered off the machine, connected the power cable and booting worked fine again. This behaviour is reproduceable.
I am not shure if I have forced the following crash because of powering off the machine, but this was the only way to get the machine running.
You can find an indicator of this crash, hopefully:

If you're never even reaching the login screen, then this xapp crash is unrelated (and relatively minor) - this program only starts after login. I'm not sure what could be causing it, though. Do you see anything helpful if you hit escape while the mint splash screen is showing (if it gets that far)?
