Import multiple PLY file meet AttributeError: Calling operator "bpy.ops.import_mesh.ply" error, could not be found

System Information Operating system: Ubuntu22.04

Addon version Broken: 2.2.1 and 2.2.0.beta

Describe the bug When I try to import a PLY mesh sequence, I receive the following console errors:

Report: Error
Python: Traceback (most recent call last):
File "/home/mtl/.config/blender/4.0/scripts/addons/Stop-motion-OBJ/[panels.py](https://panels.py/)", line 300, in execute
operator = sfile.active_operator
File "/home/mtl/.config/blender/4.0/scripts/addons/Stop-motion-OBJ/stop_motion_obj.py", line 786, in loadSequenceFromMeshFiles 
#grab the current mesh so we can put it back later
File "/home/mtl/.config/blender/4.0/scripts/addons/Stop-motion-OBJ/stop_motion_obj.py", line 419, in load emptyMeshNameElement.key = theMesh.name
File "/home/mtl/.config/blender/4.0/scripts/addons/Stop-motion-OBJ/stop_motion_obj.py", line 484, in loadPLY
numFrames = 0
File "/opt/blender/4.0/scripts/modules/bpy/ops.py", line 109, in_call
ret = _op_call(self.idname_py(), kw)
AttributeError: Calling operator "bpy.ops.import_mesh.ply" error, could not be found

Total have 4617 files, I tried to use partial of it, but still meet the same error.

Steps To Reproduce Steps to reproduce the behavior:

1. Go to File > Import > Mesh Sequence
2. Change 'file type' to 'PLY'
3. Type first few letters of the PLY sequence filenames.
4. Click 'Select Folder'
5. Receive console errors.

Expected behavior The PLY sequence should import and be playable from the timeline.

Blender 4.0 removed the old python-based PLY importer. You'll need to use Blender 3.6 or earlier until I refactor the addon for Blender 4.0.
