Elements have disappeared from my canvas

Elements on my canvas have suddenly disappeared They are there, as I can select them, but they are invisible and unable to make them visible.

Hi

Is it possible for you to save the project and send us the file? You can attach it here or send it to me via DMs (you will see the option when clicking on the name).
Also please state your OS and Lunacy versions.

I have also encountered this issue before, but it was resolved when I reopened it. My operating system is Arch Linux, and I am using Lunacy 9.1.1.
