Spinning startup screen - iPhone

For the past two weeks I have gotten a spinning startup screen. It is a black screen with a rotating circle. It does this for many minutes without end.

I have tried:

Force closing the app.

Reinstalling the app

Restarting my iPhone

Nothing works. It still continues to spin.

Any ideas?

What makes you think this spinning circle is related to an Avast app?
There are several discussions of this iPhone issue on the internet e.g. Iphone constantly going to spinning wheel… - Apple Community
