Not sure if it is the right place to publish it but I do not see any bugs section.
Anyway, I was trying Cloth brush in 2.83, everything all right, but being in Sculpt Mode, when I press N to open the right hand menu, Blender ALWAYS closed. I tried sometimes before posting here.
I know it is in alpha state and it is normal these things happen, I just want to inform to help Blender developers and contribute to its development.
Cheers and happy blending!
