Very unstable, keeps crahing when rendering animation [1.5.6]

[schroef]

windows 11 blender 4.1 v1.5.6

I noticed this version also seems very unstable. I was trying to render an animation and it keeps crashing after say 3;6 frames. I have "alwys_update" checked, perhaps this is causing it. I see its being called pre and post frame. If also tested with always_update unchecked, but still crashes within 2-3 frames of being rendered

PS why is there a scene check_always_update, when there is nothing in that panel? EDIT > found it, it checks for lock_interface but doesnt show anything else.

Attached crash report. I dont understand much here, but it keeps showing the "frame_change_post" function as last item Flag225x150_bl280-bl402-win.crash.txt
