Photos Scanning

I updated to iOS 13.3.1 When I went on "Memories", it started scanning my library and then suddenly stopped and stayed on that scanning screen until tonight. Now it's scanned 0 of my photos. When I click on the "Faces" album it tells me: "0 Photos Scanned, To finish scanning your remaining 516 photos, lock your iPhone and connect it to power.". It's already connected to power and I've locked it for Overnight and nothing happens. Does anyone know how I can get it to scan my photos on my iPhone 8 ?
