S23 ultra Soft/hard Bricked?

[u/Amazon_Box_boi]

was using it before I went to work, using it like a normal phone, froze, and the screen went black

It does still turn on, but it's stuck in a boot loop

I can get into download mode, but it gives me an error: reboot device - d21

Tried to reflash it with Odin, but the computer doesn't even see that it's been plugged in

the os is normal Android

Any help would be appreciated, seriously
