R project keeps getting stuck

I am trying to load a project and can't get it to load. If I open the project it get stuck in this infinite loop forever. Creating a new project for the data in a new folder doesn't work so I assume this is caused by some of the r files. Any advice would be great.

Could it be due to the folder being on Dropbox? What if you make a local copy of the whole project?

I assume you mean "does work"? Or am I missing something?
