The numbers in it are all multiples of 3 if that helps to decipher it, there’s also a reddit page about this code(?) At first I thought it could be a game cheat like in fight fighters but then I realised that I was being an idiot and none of those characters come up in video game controls. The only thing I can personally help with is that it’s not a ceaser cipher or atbash code but is similar to the cryptic writing in the journal 3 merchandise book.
