So this does not happen with 249.4?
No idea what causes it... Any chance you bisect this?

Yes unfortunately it's still happening with the lastest systemd version.
I'm sorry I won't be able to bisect this since I'm not that tech-savvy.

I'm still learning but do not have much time on my hands. It might take me some months.

Anyways thanks for your support!
