Unreal Editor failing to laod

I’m only 4.21 so I’m not sure if this code snippet is still accurate, but ModuleManager.cpp (Line 373) where it appears your crash is happening is:

IModuleInterface* FModuleManager::LoadModuleWithFailureReason(const FName InModuleName, EModuleLoadResult& OutFailureReason)
{
#if 0
	ensureMsgf(IsInGameThread(), TEXT("ModuleManager: Attempting to load '%s' outside the main thread.  Please call LoadModule on the main/game thread only.  You can use GetModule or GetModuleChecked instead, those are safe to call outside the game thread."), *InModuleName.ToString());
#endif

I’m assuming that Unreal is attempting to open a project of yours when this happens. Does your project include any plugins or do any manual module loading?
