Hello everybody here.
My demo packaged succesfull, but when i try to start the packaged game i only get this error message:
Fatal error: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/UObjectArray.cpp] [Line: 103]
Max UObject count is invalid. It must be a number that is greater than 0.
Does anybody know what to so ?
Hi Stucki,
I’d recommend you package your game choosing DebugGame as configuration and checking the option to include debug symbols and unreal crash reporter. At least you’ll get a callstack with your crash and from there you can point to what caused your error.

Presizing for max 0 objects, including 1 objects not considered by GC, pre-allocating 0 bytes for permanent pool.

Does this mean anything to you ? thx for helping !!
Not really, looks like now you can’t package anymore? Comparing with my latest successful package, the two differences are that I can “mount” plugin MLSDK whereas you get this error:
MLSDK not found. This likely means the MLSDK environment variable is not set.
Although that shouldn’t be relevant unless you’re using MagicLeap.
Also striking that you presize for 0 objects (penultimate log line), in my case looks more like :
LogInit: Presizing for max 25165824 objects, including 0 objects not considered by GC, pre-allocating 0 bytes for permanent pool.
If you could package yesterday, but you can’t today, and haven’t changed your project, maybe try to uninstall and reinstall the editor. Sometimes black magic work. Sometimes.
So once again, have a look at the callstack in the Crash Reporter (not the log from the packaging). Check what’s before [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/UObjectArray.cpp] [Line: 103] Max UObject count is invalid.] That should point you to the culprit.
i can still package the game. many warnings, no errors.
but when i start the packaged game …
i want to submit to a contest and have to deliver to february the eights …
and no idea what to do.
I know this is late, but this is the only topic on google related to this crash, so I’m leaving the answer here.
ERROR Message:
“Max UObject count is invalid. It must be a number that is greater than 0.” when launching packaged game.
SOLUTION:
The crash is caused by the setting “Maximum number of UObjects that can exist in cooked game”. The setting is found in Project Setting > Engine > Garbage Collection. By default, this was set to ZERO for me. Obviously shouldn’t be zero.
No idea what is the best number to use here, so I copied used the number 25165824 (This is the default for “Maximum number of UObjects that can exist in THE EDITOR”).
This resolves the crash when launching the packaged game.
