On my system (Linux), Blender 4.32 locks up and I have to kill it - Terminal: Pkill Blender.
Version 4.4 tells me that Math Formula has to be used on less than the Max Version (I guess, currently, 4.4) even though your Description says, Any Version.
I've also had blender freezing for a bit when trying to install extensions on Linux (not just with this one). I just uploaded a new version (v2.1.0) of the add-on which can be opened in blender 4.4, and contains some other fixes. Hopefully this version works for you!

So, dead in the water.
