Exact steps for others to reproduce the error

File: {F9914739}
Try moving the selected rig object with the G key. Should be fine.
Disable and enable the LTC-Cap_Lattice object in the outliner (with the screen icon)
Try moving the selected rig object again. Should crash.

First guess would be 3681a619de.

I’ll take a look.

I can confirm. Bisecting points to 3681a619de. Paging Dr. @dr.sybren to have a look.

I have merged @EvertonSchneider's report as both crashes have the same stack trace on my machine. However, #87065 has a different method to produce the error.
I have pasted the relevant information below as an additional robustness test for any fix.

Short description of error
After creating a keyframe on a simple deform modifier on lattice the blender closes on frame change.

Exact steps for others to reproduce the error

Open the attached file and create another keyframe on the simple deform modifier of the lattice.
After pressing "I" to insert the keyframe note that the lattice resets to its normal shape.
Now the crash will happen on frame change.

I found a "workaround" for this that actually works.

After the above first and second step just enter in edit mode on the lattice and it will "update" the deformed shape, now you can change the frame without crash.
