My fedora device is connected to wifi, but the wifi doesn't work

This is where something is going wrong.

1.) I am doubting that 137.0.0.63 is a public DNS
2.) DNS is usually operating on port 53, not 63

(Unless you own 137.0.0.63 locally and configured it to listen on port 53)

In any case 137.0.0.63 is unable to resolve the fedoraproject domain name - that is why you can"t access the internet.

EDIT: I see a network adapter called ipv6leakintrfe - that seems to be something related to Proton VPN that introduces a bug. Here are related topics including the solution to the issue:
