Andoid nextclod client crashes when syncronizing

hi nextcloud community

i freshly installed the latest version of nextcloud and of the android client in order to syncronize directories on my android phone. however, whenever i try to start a sync job the app crashes. i unininstalled the app and reinstalled it again. but it crashes every single time. with that said, i cannot meaningfully use the nextcloud client… that’s too sad!

is this a known issue? is there a way to fix it?

technical specifications:
Nextcloud 16.0.0
LineageOS (15.x / Android Oreo)
