Hello. I was looking for some help. Recently I have downloaded ARK dev kit but every time I try to start it up it crashes with this error message. It was a 4 hour download for me so I would leave a reinstall as a last resort. Any help would be appreciated. 
Pretty sure this was an issue not too long ago with the DevKit due to a manual update being incorrectly packaged and a binary issue.
Did you download the DevKit from the Epic Launcher recently? If so, this should not happen as that bug was dealt with an update or so ago.

Good day,
I am having the same issue, and I downloaded the devkit from steam, then the latest engine download from GITHUB and when I still get the same error, I then also downloaded a “ArkDevKitDiff_v240.5.zip” that was listed on the forums. Is the steam version download not a good place to download the devkit?

I downloaded the dev kit from steam. Will there be a fix or do I need to redownload or what?
Download it from the Epic Launcher.

I also had an issue but after verifying the ADK through steam it fixed itself, if your still having issues I would give that a try.
