I had a similar issue last year on my android, the trick I used was this
Turn off your phone (not a reset)
Turn it on, Uninstaller the app Turn off the phone
Wait 2-3 minutes then turn it back on, and install the app.
Turn the phone off again before opening the app.
Wait 2-3 more minutes, Turn the phone back on.
Wait for 2-3 more minutes and then open the app.
It's worked for me a few times why this series of procedures makes it work I don't know but it works, vest of luck to you.
