Hanging up at initial start up

Hi everyone

I’m using a Raspberry Pi 4 Model B with 8GB RAM, 2 TB Crucial SSD. Official power supply. When I try to connect via my laptop browser (Brave). I’ve got as far as being asked for a username and if I want to restore or create a new seed, and have even been given the seed words once but can get no further before everything seems to hang up. Interestingly, the point at which things hangs up varies.

is anyone able to shed some light on what my problem might be? I’ve re-flashed to the micro SD several times and I’m using the recommended case with fan.

Thanks in advance.
