Broken: version: 3.6.0, branch: blender-v3.6-release, commit date: 2023-06-27 08:08, hash: c7fc78b81ecb

Blender is crashed after calling bpy.ops.uv.pack_islands() command

Exact steps for others to reproduce the error

On default cube select something and call bpy.ops.uv.pack_islands() without using INVOKE_DEFAULT

Result:
Blender is crashed

Extra information:
P.S. It works if we are calling bpy.ops.uv.pack_islands('INVOKE_DEFAULT') but operator window is shown everytime.

Request:
I am from ZenUV addon team and we have a lot of functions based on this operator.
If it is possible, we would be highly appreciated if you could create silent version of bpy.ops.uv.pack_islands as it was all previous versions. I think there also many UV addons like MagicUV that will face the same problem

I can confirm in 3.6 but not in 4.0.
This is the crash call stack:

 	blender.exe!aligned_free(void * ptr) Line 84	C
 	blender.exe!MEM_lockfree_freeN(void * vmemh) Line 100	C
 	blender.exe!pack_islands_exec(bContext * C, wmOperator * op) Line 1558	C++
 	blender.exe!wm_operator_invoke(bContext * C, wmOperatorType * ot, const wmEvent * event, PointerRNA * properties, ReportList * reports, const bool poll_only, bool use_last_properties) Line 1541	C++
 	blender.exe!wm_operator_call_internal(bContext * C, wmOperatorType * ot, PointerRNA * properties, ReportList * reports, const wmOperatorCallContext context, const bool poll_only, const wmEvent * event) Line 1764	C++
 	blender.exe!WM_operator_call_py(bContext * C, wmOperatorType * ot, wmOperatorCallContext context, PointerRNA * properties, ReportList * reports, bool is_undo) Line 1842	C++
 	blender.exe!pyop_call(_object * UNUSED_self, _object * args) Line 305	C

It also fell for this assert:
"Damage before 0x%p which was allocated by aligned routine\n"

I can confirm in 3.6 but not in 4.0.
