After updating to 27.1.3 it returned a blank canvas, everything was gone

I am only using a few features from Nextcloud, like the handsome login and community support I can offer from inside. However, today when updating the platform reset to the beginning and all links, everything was gone! Fortunatly I made a backup and now rolled back. I like to know if this is a problem with the last update or if I’m the only one. If I’m the only one, then the issue is me somehow and I’ll figure it out :).
I appreciate all ideas!
