ATTENTION: Sync version has been changed in 2.3

I have a problem with the update. I am using windows version and a webdav personal server to sync my notes. I am receiving this message:

Error
The sync target could not be upgraded due to an error. For support, please copy the complete content of this page and paste it in the forum: https://discourse.joplinapp.org/

The full error was:
