Apologies for this. I believe this the same as MicrosoftEdge/DevTools#179 which, fortunately, has already been fixed in Edge 117 and 118 (if I'm not mistaken).
The reason this happens is that this bug was causing the Network throttling option to be set to Offline when DevTools was opened. If this still occurs to you, make sure you don't have an update of Edge that's waiting to be applied. If you do, please update the browser. You can also go to the Network tool in DevTools and change the throttling drop-down value from Offline to No throttling.

Hope that helps. Let me know if the problem persists.

That was the issue thanks. I was on Edge 117.0.2045.43, though I guess the configuration may have transferred from when I had devtools opened on an earlier version that forced Offline?

[captainbrosset]

That's very likely, yes.
