The WiFi has an IP address. Can you ping 8.8.8.8 OK? If you run:

ping -c 4 8.8.8.8

Do you get 4 replies?

OK, run:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

sudo apt update

sudo apt -y full-upgrade

Should help. Looks like you are connected but the DNS settings in your system are off or non-existent. The fact that you can ping 8.8.8.8 OK shows that traffic is flowing as expected

I think the issue is connecting to the WIFI 6GHZ channel is the issue. It can connect to 2.4 and 5GHZ channels.
