2020.3 added

I think it's impossible to unpack even they added 2020.4 and make it more complicated

I've read  the protector developer's technical blog and I have something to make sure.
as you know the code is protected with homomorphic encryption(HE)
they call their protection model CiO model.
all constants in program related states is executed while keeping encrypted so if program path completely depends on constants, it is almost impossible to achive. (....?)
I mean the problem is whether this challenge needs information that only developer knows.
