First question, you indicate in the title that you believe Thunderbolt 4 is involved, can you explain why?
A way to get around the DNS situation, for testing is to get a valid IP address you might be able to enter directly to see if you can get to a specific site. I don't remember for sure but are you seeing a "Yellow bang" or yellow triangle on the internet access in the Taskbar?
Google has some DNS servers you could also substitute for the one currently showing for your system.
If it may matter, do you have IPv6 access through your ISP?
And, of course, knowing your exact model number and current configuration could be helpful.
