Enrtopy X on PS5 crashing on startup?

Okay so I play BlazBlue Entropy both on Steam and Entropy-X on PS5. Managed to make it much further on PS5; however suddenly each time I try to run the game again, I keep getting a fatal System Failure kind of game crash that's obviously trying to act like it won't work anymore some reason now. This error seems console-wise. I've checked for updates on the game, and even uninstalled-to-reinstall it... what triggered this?
