Game crashes on iOS after installing 4.8

After installing 4.8 and launching to my iOS device, the game’s credit screen pops up like it normally does, and goes back to the desktop before the game’s title screen can appear. I don’t have any information otherwise, other than it wasn’t doing this prior to 4.8, and it does this for all of our maps, even a test map. I’m launching from the Editor to my ipad. PIE works fine. When I Launch to my desktop, this is the popup I get:

Assertion failed: !Result || Result->LinkerLoad == Linker [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.8\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 1054]

Update: This is not an issue when a full packaged project is created, only when choosing Launch>iOS device/desktop from the Editor.

Hi RHopperArchimage,

Can you see if there’s any crash for this? [Here is where you’d locate them][1].

Thanks!

Also, here is something to try, just to make sure there’s not errors in moving your project from one update to the next.

In the Engine folder, delete the DDC (Derived Data Cache).
In your project, delete the Intermediate, the Saved, and the Binary folders.

When you next try to package it will take considerably longer as the shaders will need to newly compile, but this should get rid of any old or corrupted files that haven’t gotten deleted.

If that doesn’t help, and you’re able to reproduce the crash, please post here and do include the crash .

Hi RHopperArchimage,

This issue has now been fixed internally. We are hoping to include it in the 4.8.1 hotfix but if you need it sooner (and are using Source) you can get the [Github commit for source build here][1].

https://github.com/EpicGames/UnrealEngine/commit/a1247009f0cb3a300e18001f81e000307a14cb58

The link is invalid,could you upload the source again,I think I was experiencing the same issue!
Thank you!

Hey,

That link does work. Did you log into your GitHub account? You must log in before you can see the GitHub commit for source build.

Thank you!
