Object not found in Blender 2.91.0

[proxy-auth-req]

I followed the very simple installation documentation, but it seems it won't work on my system. I downloaded the latest ZIP, installed it through the UI in Blender, downloaded the testVHACD.exe and dropped it on the desktop. Linked it in preferences and saved it. When I press F3 and hit enter to: Object - V-HACD, I get a message saying:

Python: Traceback (most recent call last):
File "C:\Program Files\Blender Foundation\Blender 2.91\2.91\scripts\startup\bl_operators\wm.py", line 1655, in execute
owner_id = workspace.owner_ids[self.owner_id]
KeyError: 'bpy_prop_collection[key]: key "object_vhacd" not found'

location: :-1

I added the exe as an exception to my Anti Virus, executed the exe to see the log and saw that OpenCL is fine. I have Win 10 64bit installed. I also ran Blender as an Admin, but didn't change anything.

In 2.93 and 3.1.2, it doesn't even show up after installing, I had to go back to 2.83 to make it work at all.
