Notes get erased when using Synology Drive (Uncaught illegal access)

I use Synology Drive to sync my Vault. But recently, sometimes the entire content of the note that is being edited disappears. An error message with the content (Uncaught illegal access) appears.

This is relatively rare when editing normal notes. When I edit drawings in Excalidraw, this happens much more often. The entire content of the drawing is gone and an error about incorrect loading of JSON appears.

If synchronization is disabled, these problems no longer occur.

I am sorry but we don’t provide support for third party sync systems.
I don’t know how they work. Moved to help section.
