[Xiaomi Pad 6] Step666:
Ok, I feel like I'm beating my head against a wall - I cannot get this ROM to work and I don't know where I'm going wrong

It seems to flash just fine, but after that, as soon as I try to boot up normally it goes into Fastboot - I can boot into recovery either via a command or volume keys but if I just try to power on normally, I get a Mi logo for a moment then fastboot

If I flash back to MIUI, it boots fine, so it's not even something stupid like a faulty volume key that's forcing it into fastboot

A couple of things I've tried based on fixes that have been suggested for other issues in this thread:

Uninstalling/deleting the drivers and using the Xiaomi Unlock tool to re-install them

Flashing back to stock MIUI before trying to flash this ROM

I even tried 'fastboot erase super' as that fixed someone else's (different) issue and I'm kinda grasping at straws

Here's a dump from the command prompt

When it says Rebooting into fastboot followed by < waiting for any device >, it reboots into fastbootd which I saw some discussion about before but that doesn't seem to cause the flashing process any issues
