MS EDGE is on edge, it can't surf, but everything else can

My MS EDGE can’t surf anymore, other browsers (Safari, Chrome, Firefox) work without problem.
EDGE Version 124.0.2478.109 (Official build) (arm64), macOS Ventura 13.6.7 on a M1 MBP.

I can easily live without EDGE, I only have it for testing purposes. But how can I research what’s going on?

Whichever site I try, it just doesn’t load anything and I get
*Hmmm… can’t reach this page *
Try:
Checking the connection
Checking the proxy, firewall, and DNS settings.
ERR_NAME_NOT_RESOLVED
