Blender 5.0 und 5.1.0 crash - Lattice and change scene

Hi, Blender 5.1.0 keeps crashing. It seems to be related to Lattice. I then installed 5.0, edited the same file, and at first there was no problem with Lattice. But when I tried to switch scenes, Blender crashed again. I’m attaching the two crash reports.

gp-character-set-rigging-animation_9344_autosave-5.1.0-.crash.txt (33.6 KB)
gp-character-set-rigging-animation-5.0.crash.txt (43.5 KB)

Can anyone tell me exactly what’s causing this and whether I can continue using 5.1.0 if I apply a fix (If so, which fix should I use, and what do I need to do?), or should I switch to 4.5 LTS instead?

Thanks, René

Check if there is a memory shortage.

Most crashes are caused by a lack of memory. :thinking:
