Memoji keeps kicking me out ??

I decided to make my Memoji (through messages) and every single time I specifically go on the “clothes” tab and scroll down, it just kicks me out, randomly. I thought it was my wifi/bars but when I navigated to the top of my screen, both were full. I don’t know if it was a bug, but it’s irritating. all I wanna do is customize my Memoji :( .
