what device are you using windows android or mac?
I'm using windows. I re-downloaded the game just encase my first try was corrupted, but got the same result
I found the issue, apparently 7zip had a major update 3 months ago and your file is the first that I've seen not compatible with the older version.
As I thought, problem was on my end, thanks for your time!
no worries, happy that it worked out for you in the end.
