Thank you for posting in community forum. 10.7.0.192.1 is the correct version of Package designer available currently. I also did launch it on my Win 10 machine and I was able to use the application and create a package (screenshot attached).
The issue could be because of OS environment or something else. Have you tried to remove the Designer software and re-install it? Also, it would be better to run sfc /scannow to check if there are any OS files integrity issues.
