Answer 1

Been dealing with this issue for a while every time I tried opening a project.

I always receive this error even though I knew I had not made any changes that should of caused this apart from exporting to zip.

To Fix:

• Make a new project or open project that works
• Go to file > open > "your project"
• Make sure your dummy project stays open. The project you were getting errors should be opened in a new window.

This fixed it for me without doing any changes or deleting anything.
