Python: Traceback (most recent call last):
File "C:\Users\plumb\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\cats-blender-plugin-master\ui\armature.py", line 205, in invoke
return context.window_manager.invoke_props_dialog(self, width=dpi_value * 3.25)
TypeError: WindowManager.invoke_props_dialog(): error with keyword argument "width" - Function.width expected an int type, not float

this is what it says and i am clueless

Maybe don't use 4.0 as cats is not compatible with 4.0 and the official one will never will be.

You could try my unofficial one: https://github.com/Yusarina/Cats-Blender-Plugin-Unofficial- though which is semi compatible with 4.0.
