System Information
Operating system: macOS-14.6.1-arm64-arm-64bit 64 Bits
Graphics card: Metal API Apple M2 Pro 1.2

Blender Version
Broken: version: 4.3.0 Alpha, branch: main, commit date: 2024-08-12 22:42, hash: ddc9f92777cd
Worked: unknown but crashes also with 4.2.0 and 4.1.0 (!! the blend file contains Geonodes using the new GPencil to curve node)

Short description of error
Blender crashes (seg fault) right on opening file created with 4.3

Exact steps for others to reproduce the error

Open 4.3
create new default particle system on cube
play animation for a few frames (space bar)
stop animation
save file
quit Blender
reopen saved file (attached as reference)

See also attached crash logs.
