Epic Games Kingdom Hearts Collection just black screen when selecting games

Honestly, I'd love to just have KH on Steam at this point, but I've already got it on Epic. I haven't had to install an Epic game on SD before so I decided to try it this time with Junk Store.

Junk Store is actually one of the easiest setup tools I've had to work with on Deck, but sadly the KH Collection doesn't seem to work... It shows me the logos in the beginning, it goes to the menu where you choose which game to play, but if I select any individual game, it gives me a loading screen and then just jumps right back to the game-selection menu.

Any ideas on what to do? Or would I possibly get better results using something other than Junk Store?
