Home Page Not Working | WordPress.org

Hi! I’m a complete beginner in wordpress. My home page started to go blank in editing mode today. I tried to deactivate all plugins and activate them one by one, and it started to show nothing once I activated Spectra. I have also tried clear cache, update wordpress to the latest version, still doesn’t work.

Can anyone help with this? Thank you so much!
