Pi won't connect to network

Hey. I'm flashing Raspbian 64bit on my Pi 4b and I have it set up to connect to the network in the config, but it isn't doing it. On the desktop environment the network icon just shows bars with an X and when I click I am prompted to set my wifi region. When I do this however, nothing happens. I have reflashed loads of times and it isnt working

Network settings is missing in raspi comfigntoo

just got it by restarting a load of times, not sure what the issue was

First, change to a power supply or USB cable that is suitable for your Pi.

yeah i am using a pretty terrible USB hub right now just because there was nowhere to plug it in near my monitor

And test to flash another SD card or USB stick

but now i'm moving it to the proper power supply
