Relume App Crash: How to Fix Global Section Not Found Error

Hi. I have a problem! I was working on an app wireframe when suddenly Relume stopped working, and I received this message Oh no, the app just crashed! Technical details:

Error: Global section 639eb3c844044822b625923caf7cf60a not found

I have been reloading the page, signed out and logged back in, but nothing has worked so far! I attach a screenshot of the page. Any ideas how to fix it? Thanks in advance!
