To fix EDGE I stole this from another wab site...
In Edge, click the three dots (ellipsis) in the top right hand corner,
then select Settings, then select Default Browser.
There is then a heading "Let Internet Explorer open sites in Microsoft Edge". In my case this had been switched to 'Always' - I switched it to 'Never' even though this isn't the recommended setting.
Then I closed Edge and opened Internet Explorer without issue.
OR.....
opened up edge first. Go to settings on the right top. Scroll down to the settings again on the drop down. When that comes up you'll see on the left of the screen a few different options. I believe the 7th one down is the option Default Browser. Click on that and on the right side a few options will come up. On the second option down it'll give you a choice to allow edge to open and all IE, or only when the IE can't open a page, and Edge can always open even if you click on IE. I put mine on only if IE can't open the page. Then I restarted my laptop. It now works with no issues.
I just fixed mine again this A.M.
