[DaLiV]

for current crashing recovery can suggest :
adb install -d com.nextcloud.android.beta_20251122.apk - that version at least starting and syncing (sure persist other issues) ...
sadly EXPORT of configs exist not, so any of such cases renders app unusable for many days/weeks or with hard reconfigurations of many setted up folder syncs ...

I should also mention that it always crash after successfully authenticate in browser, having no problem initiating the authentication process

[mr-slonn]

complete removal and reinstallation does not help.
the prod version works, but it doesn't suit me because I need a year/month/day folder structure.
