ERROR opening Scrivener

I copied my complete Scrivener folder to a second computer and got the error message below
It took longer than normal, but project eventually opened, and I see no issues. However, it worries me.

At first I thought I was using fonts not available on my 2nd computer, so I made sure my default font was installed and assigned to Scrivener default fonts.
I even deleted the title page, yet the error keeps popping up. It opens correctly in the original computer

What’s my next step?



Thank you! :smiley:
