No, didn't have time to clean your file.
But is not BIOS issue, if the one I sent you didn't help.

It did help—the machine is passing the Apple logo now but gets stuck on the login screen, so it looks like the issue is with the BIOS. Once you get a chance, could you please clean ME ? Thank you!

The BIOS I sent for test, has clean ME.
So you have another problem there.

Try starting in safe mode.
Starting in diagnostic mode may help too.
Also check if loads USB test macOS.
