I subscribe to a Youtube channel of a guy who does nothing but clean drains with a pressure washer setup and have looked at doing similar work on my own house and it’s actually pretty reasonable (like $120). I’m sure OP spent more in time and money than that and could have possibly damage their plumbing with the chemical cocktails.
From watching enough videos, OP’s clog may have been from wipes, sanitary products, roots, grease/fat, or a broken pipe. Almost none of these can be fixed with chemicals.
