Crash after Launch on desktop Assertion failed: AsyncLoading.cppLine: 1776

Hi,

I have encountered weird issue with function Launch on Desktop. Play in editor as well as build on any platform works fine.

Build results in no errors, immediately after application launch there is following error:


ProcessResult.StdOut: [2020.04.10-00.00.00:300]  0]LogWindows: Error: begin: stack for UAT

AsyncLoading.cpp Line:1776

        // @todoio: why do we need this? some UFunctions have null outer in the linker.
        if (Import->ClassName != NAME_Package && !bIsPrestreamRequest)
        {
            check(0);
            continue;
        }


I have 90% of my game in Blueprints and a few nodes in C++, nothing crazy. Mostly simple features and some overrides of the engine classes to expose some variables.
Couldn’t pinpoint an issue by removing/commenting code as I created a lot of code since my last launch

My Specs:
UE4 4.24.3 - Launcher build
Windows 10

If you have any idea where the issue might be present please let me know!

Note: Play in editor as well as build on any platform works fine.

Getting the same thing building for Quest with oculus-4.25.3-release-1.52.1-v20.1
