Cannot access internet from kali linux when on NAT network

I am a beginner in penetration testing.I am currently following an online course, but I am having trouble configuring the network settings.

I have internet connection on kali linux when in NAT, however when I change the settings to NAT network, I no longer am able to access the internet through kali linux.

I have changed the proxy settings to "no proxy", but that didn't change the situation.What else should I do to fix this problem?Thank you in advance.
