subiquity installer is crashing on the normal installation

It offers updated subiquity which I installed but the result is the same.
installed: 23.09.1 (5097) 19MB classic
The original installation got 23.08.1

The installation goes on the physical hardware
HP Proliant DL380 Gen10 Server
with multiple discs and network cards

I was able to configure network and drop to shell to gather information

Here's excerpt from log
