@Lottie will explain more on Logfox. But -
I think restoring your sync has priority over debugging: did you see the question on 2FA or password change? it should be enough to update the credentials in the murena account to get things running for you again (small video guide → zoomed too much in default view, use Download). Make backups of both Notes (in Settings → Export) and Contacts (Settings → Export too) anyway before change.
File sync needs this checkmark. Contacts, Calendar, Tasks and Notes should work after credentials update immediately.
