Edge stopped working after latest Dev update

julianonunes Weird: someone else just posted a very similar issue in another thread, but based on Edge Dev 78.

This article talks about some sandboxing restrictions that started in 78 & some incompatibilities:

Here's a longer thread with similar and a few other solutions: https://techcommunity.microsoft.com/t5/Discussions/This-page-is-having-problems/m-p/816671

Would any of these fix your bug?

I'd definitely submit a Smiley, too: the more reports (and debug data) they can get, the better. If there is an incompatibility, there should be a far more graceful failure. This bug fails in a pretty destructive and unhelpful way.
