Big Sur - Prohibted Sign

Hi there,

Trying to install Big Sur from a external USB onto my SSD however during the install it completely freezes at 12mins

EDIT: I've tried to update directly from Catalina, however once my PC reboots, and I try to open the BootMacOS Install it just shows the prohibited sign
