Blender Version
Broken: version: 3.2.0, branch: master, commit date: 2022-06-08 10:22, hash: rBe05e1e369187
Works: Blender 3.0.1

Short description of error
Add-on Btracer > Particle Trace not working in Blender 3.2.0
Blender version tested on: Blender 3.2.0
blender-3.2.0-stable+v32.e05e1e369187-windows.amd64-release.zip

Bug Repro Steps:
Open Blender 3.2.0
Enable the Btracer add on
Select default cube
Add particle system. Emission > Number > 20
In Layout view press n key and select Tool > Create > Btracer
Btracer > Choose Tool > Particle Trace > Settings > Curve Settings >
Spline > Bezier
Handle > Vector
Click "Add Grow Curve"
Accept defaults and click Run
Nothing happens. No particle traces occur.

This all works in Blender 3.0.1
I can open older files from 3.0.1 into Blender 3.2 and they work.
Problem > any attempts to create NEW btracer effects in Blender 3.2 won't work.

Below is error from console window:
[Btrace]
particles.particletrace: Operator
Error: SplineBezierPoints.add(): error with argument 1, "count" - Function.count expected an int type, not float
