kubuntu 25.10 installer fails

[lopgok]

My laptop is unable to install kubuntu 25.10. I have also tried 25.04 as well as 24.04 without success.
It is able to install windows 11 25H2 as well as mageia linux 9 without issue.
The live version of kunbuntu 25.10 starts up.

I have a HP laptop, model 17-cn0273st. It has a intel i3-1125G4 cpu with integrated graphics.
The laptop is running the latest bios, F34 (installed jan 2026). It has 32gb of ram and a
500gb ssd hard drive. It is about 5 years old.

I partition the disk, and the install starts. The progress bar gets mostly dune, and then an error pops up saying
Installation Failed
Boost.Python error in job "displaymanager".
there is a lot more text. I am including a screenshot.
