Can't find the specified file error message...how to get rid of it?

Hi everyone!

I have one project that always gives me the "can't find the specified file" error message.  I am not sure if this is because I moved Studio projects to OneDrive and moved them back to local drive a few days later (I did remap the project templates).  I already tried the suggestions found in another similar thread by renaming the Studio folder, restarting Studio and also restarting the computer, but the message still comes up when I open the project.  

Is there a way to get rid of the error message?  Thank you so much for your help.
