System Specs: macOS 10,14,6 2 x 2.4 GHz 6-Core Intel Xeon 128 GB 1333 MHz DDR3 Radeon VII 16GB

Blender is crashing when I click "Bake" in the physics tab Console gives this output:

I do not experience crashes when I deactivate AN

[OmarEmaraDev]

Can you attach the rocket_023.crash.txt file here?

[L33t-HAXXOR]

This one? I mades a rocket_023.crash.txt

[OmarEmaraDev]

@L33t-HAXXOR Yes. Blender is crashing on depsgraph evaluation. This seems like the same problem users have. Are you sure it still crashes with locked UI? Do you have multiple scenes?

[Gerstmann-Bradley]

Or I think you may bake everything into keyframe, disable AN Execution and then bake physics.

[L33t-HAXXOR]

@L33t-HAXXOR Yes. Blender is crashing on depsgraph evaluation. This seems like the same problem users have. Are you sure it still crashes with locked UI? Do you have multiple scenes?

I only have the one scene and I have tested it with locked UI enabled A weird thing (that I can't reliably reproduce) is that in 2.93, if I spam the process enough (reopening Blender, clicking Bake), it will indeed bake on the last try

However the drivers I have attached to my object constraints only present in the sliders they are attached to but do not move the physical objects in viewport

For example, I have an empty contained to path on a curve object. I drive the offset using #frame. The numbers scroll along as normal in the properties panel but the empty itself does not move at all. This issue does not happen in 2.83

What I ended up doing was brute forcing the Bake in 2.93, saving the file and then opening it in 2.83 and rendering with the drivers

And forgive me if this should be a separate issue

[OmarEmaraDev]

Can you share a minimal file to reproduce the issue?

[L33t-HAXXOR]

I mades a rocket_023.blend.zip

[OmarEmaraDev]

@L33t-HAXXOR I can replicate the crash. It seems Blender force lock the UI all the time, so that's probably not the problem. We hit an assert immediately in the AN thread through, so that might give us a hint. I will have to look into this in more details later. But it probably will not be an easy fix.

[L33t-HAXXOR]

Thank you for looking into it!
