Cant access my Edge since I crashed it

In an effort to obtain more vivid colours I went into

edge://flags

color

and selected sRGB which was fine.

Because it was so simple, I figured I'd go in again and select the next on the drop down menu but as soon as I did Edge crashed and I cant get back into it nor does it respond to anything.

Can someone please advise me what I should do?

I have tried to reset it, but the problem persists.

I'd be happy if it was reset back to factory specs, even if I lose all the other stuff, its no big deal

Please help, I love Edge
