I would like to get the 20190705 version of pkex, but the older version is no longer available for download and I need help

Why do you need this version in specific? PKHeX does not remove features, and each update fixes hugs and adds new features.

If you absolutely must download that version, you're free to download the old commit and build it in Visual Studio yourself, release builds for very old legacy versions are not available.
