Engine crash when opening any blueprint - Ran out of memory

I’ve just recently ran into a problem. My engine starts and runs fine, however whenever I try to open any blueprint I get a fatal error:

Fatal error: [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.7\Engine\Source\Runtime\Core\Private\GenericPlatform\GenericPlatformMemory.cpp] [Line: 54]
Ran out of memory allocating 18446744073709551576 bytes with alignment 0

I am running an i7 processor, 16 gigs of ram, and 4 gigs of video ram

The strange thing is that this only happens in this one specific project. All of my other projects are fine even when opening blueprints bigger or similar in size. When running the engine I have an average of 12 Gigs of Memory Available and 4 or 5 Gigs free.

I have already tried verifying my version (4.7.6), completely deleting and re-downloading a known working state of my project and of course clearing cache’s and doing all that is possible to free up even more memory.

Please let me know of any answers or tips you may have to help my problem! Thanks a ton!

Hi ,

Is there any other info about this project that you can provide? Is it a custom project, one of our samples, or a modified version of a sample?

Also are you running a Binary or Source(github) build?
