Crash on 4.15 Launch Preview

Development Getting Started & Setup
, , , , ,
1

My Steps to reproduce:

  1. Download 4.15 Preview Set 4.15
  2. Preview as Active Launch 4.15
  3. Preview Launcher does not make it past 0%

I have verified the version but it still crashes on launch.
Other projects from 4.14 are not affects and they still load.

Hi ,

Close the Launcher and see if you can open a blank project in UE4.15 Preview by right-clicking the UE4Editor.app and selecting “Open.”

Location: UnrealEngine>4.15>Engine>Binaries>Mac>UE4Editor

If it opens to the point where you can select a project or start a new blank one, start a blank one first and then try to open a copy of a UE4.14 project once you’ve established that you can open the UE4.15 Preview. You may need to restart your Mac to start “fresh.”

Let me know if this resolves the issue.

@,

I’m guessing that we should just wait for a patch on this one and there is no workaround?

Best,

There is no workaround that I’m aware of, however, this has been fixed for the next Engine Preview.
