Crash when opening levels

I’ve worked on a few projects in last weeks and after I close UE4 and run it again and try to open a level it crashes. It never crashes during work on a level in a new project. I’m running OS X 10.9.

SIGSEGV: invalid attempt to access memory at address 0x3

EngineCrashHandler(FGenericCrashContext const&) Address = 0x552c68f  (filename not found) [in UE4Editor]
PlatformCrashHandler(int, __siginfo*, void*) Address = 0x563966f  (filename not found) [in UE4Editor-Core.dylib]
_sigtramp() Address = 0x8758bf1a (filename not found) [in libsystem_platform.dylib]

I get this exact crash every time I open LandscapeMountains demo, I tried deleting everything related to that sample, redownloaded it , created a new project and it still crashes. Every time I try to open it…

Hey all,

We’d like to get some more information from you regarding this crash. Please follow guidelines for submitting a bug report found here:

Specifically, we need your crash logs and system information, as well as version of engine you’re running and what kind of project it is (code based or blueprint only, or derived from source). Please also be as descriptive as possible with events that lead to crash. Thanks!

Hey everyone,

As explained in this thread, we inadvertently released a 4.4 Preview rollback patch. If you Updated your 4.4.0 install last week, that is likely cause of this crash. Updating back to 4.4.0 should fix problem, as it did for other users with a similar crash (SIGSEGV… at 0x3). Please try Update and see if that prevents crash from reoccurring.

Thanks,

Jonathan

I remember having that problem before this version. I’ve updated back to 4.4.0 and it still crashes.

I understand. Please give information he requested so he can continue to provide assistance.

Everything works fine on Windows on same Mac via Bootcamp.

Branch: Binary from UE Launcher
Build: 4.4.0-2255576
Project type: FP Blueprint
Detailed description of issue: I open a project in UE Editor and as I open a level that I’m working on it loads it just fine. But if I try to use editor it crashes. Always reproducible.

OS X 10.9 and OS X 10.10, 2,7 GHz Intel Core i5, 8GB RAM, Intel Iris Pro 1536 MB
