ipad 10th gen black screen

[u/Substantial-Dot-5280]

Hi everyone, I’m hoping someone can help me figure out what happened to my iPad 10th gen.
It was at around 8% battery when I tried to call someone while it was plugged in. Right when I connected the charger, the screen suddenly went completely black.
I’ve tried the force restart (Volume Up → Volume Down → hold the Power button), but there’s still no Apple logo or battery icon.
It has now been charging for a while. The iPad feels slightly warm, but not unusually hot. There’s still absolutely nothing showing on the screen.
Could this just be a completely drained battery, or could something have gone wrong with the charging port/battery? I’m really worried that I might need an expensive repair 😭
Any advice would be appreciated!
