Edge Crashed. Help

[Sundowner]

I made a mod (edge://flags/colour) to Edge and it crashed.

I cant get into it to remove the modification.

Despite trying to "reset" it and "repair" it, each new generation stays the same, because they all contain the modification I made. 

HELP

Any advice is very welcome.

Right click Edge icon and click on new inprivate window. type edge://flags/ in the addrress bar press enter. If it is all black move your mouse along the top of the web page until the reset button is highlighted and click it, then close the window, and reopen.

Reset button is on the top right.

Hope this helps.

I'm sorry asdy4 but it hasn't helped. When I try to open anything, right click or left, all I get is a blank.
Thanks for the advice though,
Cheers
