The issue you are facing:

Hello all,
I’m running 3.4.1 Windows clients across a number of machines. Almost all of them keeps crashing while syncing. As soon as I mouse over the system tray icon, it disappears. The only way I can restart it is by restarting Nextcloud.

Interestingly enough, if I let is go, it does finish, but that leads to so many errors about it not being able to sync because the metadata is invalid of invalid time stamps.

I’ve also run occ integrity and file scans. I’ve updated my docker install to the latest. No dice.
Please help. Thank you.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Start Windows client (3.4.1)

I have the very same problem. Have a look at the Windows event log, and past your crash info from there.
