I was transferring multiple groups of files when my file manager froze. I forced my PC to shut down and when I restarted it, I got a 0x78 error code. I can access the BIOS and attempted to boot from a USB drive, but I still got the same error. I also tried disabling fast boot, yet the problem persists. Secure boot can't be disabled and CSM can't be enabled. I have the AMD fTPM switch enabled and have activated the option to erase fTPM NV for a factory reset. What should my next steps be? Is there any other information I need to provide? Here are my specs: AMD Ryzen 7 5800x, 16GB RAM, BIOS model G10DK, Version 310 x64.

Sounds like you're dealing with a tricky issue. Just to clarify, is that error 0x78 or could it be 0x7b, which often indicates an inaccessible boot device? It might be worth checking your HDD since you mentioned you recently installed a new one and were transferring files to it. You could also try completely disconnecting your storage drives and see if you can boot from the USB alone without any drives connected.
Just a heads up, messing with BIOS settings or disk configurations can risk your data. Always confirm you have backups of anything important before making changes. And if you haven't already, do check the FAQ threads on troubleshooting Windows 11 issues; they can guide you on steps to take in situations like this.
