Can you change your DNS again to test? Just pick Cloudflare (1.1.1.1) or google (8.8.8.8) or something. It’s plausable that you actually can connect to the internet and are instead just unable to perform name resolution. Presumably the vpn is using a different dns server, hence it solves your problems when connected.
Or I guess you could try to ping a known good ip to see if the dns is the problem. I just pinged google and got this if you want to try it. 142.250.72.14
