Edge Dev (latest version) crashes when autofill tries to open

Hey there,

Yesterday i spoke with a guy from Microsoft's Support (the official one ofcourse) for like.. 4 hours... trying to resolve my Microsoft Edge crashing and the autofill on several websites (including microsoft.com itself) to not function, like.. it pops up but i can't press any of the saved items.

Does anyone.. have a clue at all? The Support person already tried reinstalling, clearing cookies, cache, extensions etc etc.. it's just not working.

I'm honestly clueless.
