Use top trainer as is
I have no other suggestions
I already posted why it may not work and what to try
Blame the developers for using a garbage mono language and crap coding method

SOrry to be so blunt, but I have no solution for you.
RUn game, toggle on at main menu. If it doesn't work, it wont work and there's no way for me to "fix it" if the game compiles differently on your computer machine.
They moved to il2cpp from mono which helped, then inexplicably went back to mono setting up this entire problem again, and forcing us to start over and have to make this trainer from scratch all over.. for the third time.
if it's too much issue or complaints or people cannot get it to work, then we will just retire it and move on so that it isn't something that causes grief constantly
best,
