My edge browser kept crashing so I did a system restore. This said it hadn't completed so did it in safe mode and that worked. Now edge wont even launch. Also cant open windows setting which most solutions I have found require as a start point.
You could try reinstalling Edge, see this link How to Reinstall Microsoft Edge Browser - All things technical - tips tricks
From this thread Sept. 2015 Edge won't start Exception code: 0xc0000409 - Windows 10 Forums
You might look at the thread first to get an idea of what those members did, it did resolve their problem.
Good luck :)
Edit: use the link for How to Reinstall Edge from this post, the link from the older thread doesn't take you directly to the right page.
Tried but on entering
C:\Users\trevor\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\RoamingState
I get inoperable file
I got into settings ran some windows updating, restarted machine now I cant get into settings or system reset. Just want to reinstall windows now.
No none of the googled methods worked, but have just rebooted again and now downloading a windows cumulative update so we'll see what happens after that.

I'd recommend trying an in-place upgrade repair install first. You'd only need to perform a clean install should the repair install fail to return Edge to full, normal operations. Here's a link to @Brink's excellent TenForums tutorial on that subject: Repair Install Windows 10 with an In-Place Upgrade.

Also I am downloading the windows updates troubleshooter but that wont run.
I have a message in updates Some settings are managed by your organisation
