Unable to create a component anymore, says Unknown Element

Hi guys, just openend a project after a while and i in the studio now i can not create components anymore it says “Unknown Element”:

Plasmic cannot determine which layer the the clicked element belongs to. This happens typically on code component where Plasmic doesn't know the structure of the DOM in the component.

Never seen this message before

this happens also wenn i create a new component and dont use code componenets. just clicking the base variant gives me this error

it doesnt happen when i create a new project but my currnet one is literally unusable because all of my components throw this error

Can you DM me your project id?

did so thanks
