Linux crash after Linux Mint upgrade

[bazza2jw]

BlendAR worked with Linux Mint 20 but after upgrading to Linux Mint 21 it crashes probably when creating the image window. Both with webcam and file input sources.

GDB traceback below.

Thread 1 "blender" received signal SIGSEGV, Segmentation fault.

Ubuntu 23.10 (Haven't tried it on previous releases)

Error when clicking start detection (camera)

OSError: Cannot open webcam

When using a video file it creates someting and then Blender crashes instantly
