I think the accepted wisdom is to unplug the wall wart from the wall, count to 10 (optionally pray) and then plug the wall wart back in. Presumably replugging from the mains resets the PD circuitry in the power supply after which it might negotiate properly 5A mode with the Pi 5.Same issue here,using a normal usb flash drive hangs the system,booting from memory card,using official power supply 5v/5a the setting usb_max_current that supposed to be only if you use the pi4 power supply does nothing.
Tried different flash drives usb 2 usb 3 no difference.the system hangs when I plug the drive in any usb port.
Note in the UK many mains outlets have a built-in switch to allow convenient resetting of Raspberry Pi power supplies.
