Firefox 145 and es-140 in release 14.2-Release Segmentationfault in headless

I try hard to use firefox in headless mode for a python selenium project. On other systems i have no problems.
But here in this setting when i start firefox it always complains about GPUs and the absense of a a X-Server, but this is a headless mode and crashes with a segmentation fault.

The output when i try to start is :
"
firefox --headless
*** You are running in headless mode.
