Can't open saved .cubik files [Solved]

Hi there, i'm currently running cubik.studio on my Mac, and whenever I save a file in a .cubik format, I can't open it again. This pops up:

I've tried opening it with CubikUpdater as well, and I get that same warning.
Help would be appreciated, thanks in advance!

This issue was solved by using the File > Open option inside of the application.
Thanks!
