Debbie is having problems opening the Microsoft Edge browser. It opens fine on her husband's account, but not hers. Leo says that browsers are vulnerable to that and if there's an improperly cached file, it won't open. A bad extension could also cause it. Resetting her browser may fix it, and she can do that from settings.
It could be that Debbie needs to repair it. It won't affect her app data, but if that's the problem, it may not fix it. If that doesn't work, then her only other choice is to uninstall Edge and reinstall it. To do that, she'll need to boot into safe mode. thewindowsclub.com has instructions on how to do all three.
