Packaged project crashes when entering a level from the main menu level UE5

Hey @ShakaBond,

As priority 1 (because this may be the actual root cause of the issue), there are actually several errors that look like they need to be addressed.

LogWindows: Failed to load 'aqProf.dll' (GetLastError=126)

LogWindows: Failed to load 'VtuneApi.dll' (GetLastError=126)

LogWindows: Failed to load 'VtuneApi32e.dll' (GetLastError=126)

Here is a thread with the same error that solved how to correct these files:

There is also:

LogWindows: Error: Assertion failed: FMallocBinned2::FPoolInfo::IsSupportedSize(Size) [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Core\Private\HAL\MallocBinned2.cpp] LogWindows: Error: Invalid Malloc size: '105369866224'

Is your project using the built in Malloc_Verify like in the following post?

I would address the top issue first and foremost just in case it is causing the second.

I hope the above points you in the direction you need!
