Crashing on launch

When i open my project it appears this message:

SIGSEGV: invalid attempt to access memory at address 0x3

EngineCrashHandler(FGenericCrashContext const&) Address = 0x8b5a38f (filename not found) [in UE4Editor]
PlatformCrashHandler(int, __siginfo*, void*) Address = 0x8c8b4df (filename not found) [in UE4Editor-Core.dylib]
_sigtramp() Address = 0x91d29f1a (filename not found) [in libsystem_platform.dylib]

How can i fix it? I really need to get my project back as soon as possible in order to submit it for university.

Thanks.

Hey Giorgio,

Please attach your crash logs and dump file for project after this crash occurs. You can read about where to find that information here:

Thanks!

Hi GiorgioBufa,

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing issue you reported, please respond to this message with additional information and we will offer further assistance.

Thank you.

If crash was happening in 4.3 but not in 4.4, then we probably found bug in 4.3 and fixed it in next release (4.4).

That log file doesn’t appear to be a crash log. It’s a text document saying “Just a record of success.”

Sorry if i didn’t write anything. I managed to solve problem converting project from 4.3.1 to 4.4. But i’d like to understand anyway way my unreal is crashing just on versione 4.3. crash is always at start when i try to open project. Let me know if you need further information
