Unable to import file to Insta360 Studio, getting 1 file(s) ignored message

Hi, I am having problems importing 2 files into Insta360 Studio, if I double click on the .insv files, It will show "0 file(s) imported, 1 file(s) ignored" on the button of the insta360 Studio window. I get the same thing if I try to do an import from the Insta360 Studio software. What is weird is I did open those exact 2 files before with not problems. Any ideas what can be the cause of this?

Cheers

Dan
