Ios app crashes again

App crashed when i just installed it and tried to sync all camera’s data. Any suggestion?
last version app 2.9.10
iPhone OS 12.4.8 (16G201)
AppVariant: 1:iPhone7,2:12
idk how to attach crash log here and links aren’t allowed, so:
replace underscore with dots in link

I tried Seafile today and iOS Auto Upload. Self-hosted, docker, 7.1.5.
I have 38K photos. After about 20 minutes of uploading, the app crashes and next thing i see is my iphone home screen. Try again: Same crash.
Too bad. I’m looking for just basic iphone photo & video auto-backup.
