BORIS crashes when I load a video and does not generate any error message

[marie1203]

Indicate the version of BORIS
BORIS v. 8.27.1 - 2024-06-11

Describe the bug
When I try to load a video for a new observation, BORIS crashes without any error message even if I set the MPV player hardware video decoding option to No. I tried to play the video with mpv and it works normally. I've also re-encoded the video (originally as mp4) but the same error occurs. I'm a beginner on Linux so I don't really know what's wrong and how to solve it.

In case of crash attach or copy the content of the boris.log file (before relaunching BORIS).
