Storyboard PRO 6 Unable to read error

at first i use to save my project in my hard drive. I forgot to bring my hard drive with me, so i decided to save my project in my iMac. But when hitting save and/or open the file, it gives errors. Please help! Got a deadline! D:

Update: sooo after many attempts what i did was copy the project folder and paste it in the desktop. And it finally opened. But i still dont understand doesnt open or save correctly where i previously had the project file…?

Can confirm in the year 2023 with the latest storyboard pro that for whatever reason my file also worked by copying it specifically to the desktop. Also had exact same errors with tvg read issues as well. Zero clue why the desktop is a magic zone for these problems. needs to be fixed
