Kernel 5.10-rc5 fails to boot
Kernel 5.10-rc4 successfully booted

The message after trying to boot is:

Failed to start Load Kernel Modules.

Emergency root console cannot be opened, follow-up error is:

Cannot open access to console
as the root account is locked

Journalctl -xb-1 has to say this fatal errors:

Nov 28 09:20:46 ebola mount[332]: mount: /boot/efi: unknown filesystem type ‘vfat’.
Nov 28 09:20:46 ebola systemd[1]: boot-efi.mount: Mount process exited, code=exited, status=32/n/a
Nov 28 09:20:46 ebola systemd[1]: boot-efi.mount: Failed with result ‘exit-code’.
Nov 28 09:20:46 ebola systemd[1]: Failed to mount /boot/efi.

and

Nov 28 09:21:02 ebola systemd-modules-load[476]: Failed to look up module alias ‘crypto_user’: Function not implemented
Nov 28 09:21:02 ebola systemd-modules-load[476]: Failed to look up module alias ‘uinput’: Function not implemented

I don’t know which one of the two fatal error messages causes the system not to boot up properly

RC kernels could and will fail till they reach maturity.

Do not worry, kernel developers know. Use a stable kernel for your system.

I had the same issue but when going from 5.10 back to 5.9. I had to boot into 5.10, reinstall 5.9, and then boot back into 5.9.
