Not booting stock linux

The RGDS has been stuck on the "Begin your next adventure with Anbernic" for who knows how long.

I use the MicroSD Card that it comes with to play but yesterday it has stopped working and I've tried almost everything to make it work.

I have tried:

1. Taking the card out and back in

2. Opening the android version and then opening the Linux version

3. leave it alone for 10 minutes on the boot screen

4. Leave it off for hours and then coming back

5. Restarting it

If someone knows what I could try then that would be really helpful as I don't know what happened
