Prime Video App Won't Launch

If I press the Xfinity button on my remote and go to Apps and click on the Prime Video App it launches and you get a blue screen with the Prime Video logo and 3 white dots on the bottom.  After a couple of minutes the 3 dots go away but the blue screen stays and does not go away.  If I press Exit and get out of it and then press the Xfinity button and go to Settings then Help then Reset, my cable box resets.  I can then go back to Apps and press the Prime Video button and it loads normally.  But the next day when I turn on my tv and try to load Prime Video I have the same problem and have to reset the cable box again.

I am an Amazon Prime member and when I can get it to load it works just fine.

I do not have this problem with any other apps such as Netflix or Youtube.

I do not have this problem with any of the other 2 tvs in my home.

I have reset my cable box, got into my Prime Video app, and logged out of this device and logged back in but I continue to have the same problem.

There is button in Xfinity/Settings/Help named Reset Netflix.  Is there a way to Reset Prime Video?  Is there a way to uninstall the Prime Video app on my cable box and re-install it?
