I am posting this info in the hopes it may relieve somebody else's frustration a bit:
I too had problems with Edge opening then closing for 1 username only. I followed instructions from several places but could not actually get Edge to reinstall for this user. Finally I added this user to the Administrators group. I also deleted the folder C:\Users\ < username> \AppData\Local\MicrosoftEdge as well as the folder mentioned above (...Packages etc). I then reinstalled Edge using the instructions above (be sure to run Powershell as Administrator). The user account was then set back to Power User.
Edge now works correctly for this user.
