Hey Bio,
Thanks for getting back to me and I'm sorry this is still ongoing. The only reported issue we've had with the game not opening is due to a corrupted download (the download gets paused, interrupted, phone goes to lock screen while downloading etc).
Outside of that, you could try the Joiplay method. It involves downloading the Joiplay app but the PC version of AHITR. I haven't tested it myself personally and it can be finicky but it's been known to work for people.
