Blender Version
Broken: 3.6.3 RC and Current 4.0 main
Worked: July 27 4.0

Caused by 56659f1510

Short description of error
A production file that uses a GeoNode set-up to mimic the effect of a shape key only seems to continue working as intended on specific Blender versions.

July 27 4.0: Mesh looks as intended; Pose is mostly achieved with the rig, then the GeoNode modifier is responsible for a slight correction, sculpted by an animator. (Excuse the fact that this looks horrible nonetheless, the original camera angle for this shot is from behind, but this angle shows the issue better in subsequent pics)

3.6.3 RC: Mesh completely explodes

Current 4.0 main: Mesh is actually not affected by the GeoNode ShapeKey set-ups at all. This zig-zag shape is caused by what may be a separate issue, in other geonode set-ups, in helper objects. May need a follow-up report, but for the sake of this report, just note that the locally added modifiers have no effect. (Mesh looks the same even when the "ShapeKey" modifiers are removed.)

I can't confirm this in today / yesterday builds.

3.6.3 RC: Mesh completely explodes

Can not replicate either

**System Information**
Operating system: Windows-10-10.0.22000-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3050 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 532.03
3.6.3, e362a2f0d41f

Current 4.0 main

Can confirm the difference in 4.0. (Won't be able to bisect though, lite build crash while reading the file)
