This bug blocke completly my Nextcloud upgrade.

To reproduce 👍 Nextcloud 23.0.5 installe
LibreSign V

Update Nextcloud to the next version (Same result with an update from Web or OCC cli)

I've decide to completly remove the plugin and re-install the V4.1.1 from github repo.

That's work.
I don't know why the upgrade of Nextcloud was blocked by the plugin
