I mean the “Launch” button on toolbar of UE4 editor(deploying game on Windows platform). It worked successfully only once, then I kept getting this issue when clicking on the “Launch” button. Even after I tried creating a new simple project, the same issue continues.
However, File->Package Project->Windows from the menu works properly.
Hi Awesome_Junior_Miss,
The Launch On crash from both Windows and Mac is a known issue for the current 4.8 preview releases. For reference, the JIRA for the issue is UE-15445. It has been fixed with the intention of getting it into the 4.8 release proper, however I don’t know if it will make it into any of the subsequent previews.
Thanks very much for your report!
