considering this is a Unity game, i doubt the bugs will ever be fixed. even using AOB methods, they'd still break with core files updates. the only "safe" way to have a proper, working trainer would be to have it made as a game mod. best example of this would be the trainer mod for software inc. the only existing mod of this type is in chinese though and unless someone is good at translating, it's doubtful we'll ever get a proper, lasting trainer. i doubt you'd have a stable version of this game within a year, even though it was in beta testing (*cough* early access *cough*) for well over a year (since january 2019)
Plenty of unity games that we don't have to update over and over, and that aren't patching daily.
We can hope for the best, but in the current situation, this game is being programmed by people who want it to be X but only know how to program Y.
best,
