Just ran headlong into this as well. I'm glad I did my workstation first
as my VM host is running the same config and my whole network would now
be offline had I applied it there.
I concur with raising the severity of this bug and eagerly await a fixed
package.

Hello,
I can confirm that systemd-networkd from the systemd 257.8-1~deb13u1 in
stable crashes on configurations with VLAN-aware bridges with a similar
stack trace to the one given in [0]. I have also seen this crash in one
of the Debian v258 RC's.
The problem seems to be that v257.8 is missing the fix in [1] that was
released in v257.9.
