Just in case you don’t have the debug data yet: Amaze 3.1.1 in vanilla FPOS 1.10.1, try to get write access on your external SD card (if you don’t have already).
Before you can even make the top folder selection, Amaze is already gone.
I did not suffer any crash until I enabled the Back navigation option in Amaze settings. Bug seems to be reproducible in my FP2, at least, running FP Open, latest version of Amaze from F-Droid
