HELP! I can't make edits to my document anymore

Hey there, I’m not sure what I did but for some reason I can’t make changes to my page anymore. The selector isn’t letting me select items. The undo button undoes changes but doesn’t change the state of the webflow document back for me. It seems to be in some sort of other mode that won’t let me make edits.
How do I get back to working on my page?
Not sure if the UI will be the same for when I share the link but here it is anyways.

Here is my site Read-Only: LINK
