Windows 10: Trouble starting apps

I've been having trouble starting apps the last couple of weeks and need some advice on why this is and how to fix it.

For example, Thunderbird is almost impossible to get started and no technique works consistently. Sometimes it finally launches if I click the icon a bunch of times very quickly, sometimes even that doesn't work. The last time I tried it, I got a tiny frame fairly quickly containing only the Thunderbird icon, a minimize, maximize and close button and nothing else and no matter how long I waited, it wouldn't proceed beyond that. I couldn't enlarge it with the arrow keys and the maximize button was greyed out. I had trouble getting Edge to open too.

I really NEED Thunderbird to work since I use it a lot during the day so I'm hoping someone can help.

Windows Version: 2004.

Supported phones for Windows 10 Mobile Insider Preview


Your list confirms my phone is eligible, Lumia 521. The windows Insider App fails after ~ 15 seconds, restores data and gives me error 80073cf9. I trouble shot this and went thru all the steps mentioned on several websites including MS without any luck. Short of a hard reset, this is where I am now. Suggestions appreciated.
