Nextcloud Update from 19.0.0 to 19.0.2 fails on Synology DSM

My Nextcloud instance is installed in a Synology DS918+ with the current DSM. I am trying to update NC from 19.0.0 to 19.0.2 by using the Updater function. It checks the prerequisites without issues and shows “Continue update”. After that, it shows: " [Go back to your Nextcloud instance to finish the update". By pressing this, it goes to the “files” app page without doing anything.

Has anyone observed this and is there a solution?
