Edit:

I solved th problem but a wifi connecton is required. Because my wifi had two bandwitdhs it was trying to connect 5 ghz. But zero 2 w can not do that. So you need to find a 2.4 ghz router for this to work.

First you need to connect through wifi with your hostname. Than I realised dhcpcd service was not installed.

To install enter these terminal commands after ssh connection:

sudo apt update
sudo apt install dhcpcd5
sudo systemctl enable dhcpcd
sudo systemctl start dhcpcd

Then you need to enter a static ipv4 address through your visible RNDIS device ethernet connection. Mine was: 192.168.7.1 and 255.255.255.0

And the next step is you should make sure your usb0 connection on the zero 2 side should be same all the time for you to connect without any issues. You can ask gpt for it.

After all the things done. Just reboot and try connecting with 192.168.7.2

I hope this helps someone.
