When Attempting to package my game, I get this error:
UATHelper: Packaging (Windows): LogInit: Display: LogOutputDevice: Error: Ensure condition failed: QueuedRequests.Num() == 0 [File:D:\build++UE5\Sync\Engine\Source\Editor\Kismet\Private\BlueprintCompilationManager.cpp] [Line: 1633]
I had this issue and found the solution by backtracking through the whole project and figuring out if any blueprint class has any problem.
In our case the problem was a bad cast node, A blueprint was casting to a Thirdpersoncharacter class which was not being used in the project. Removing that fixed the issue for us.
I saw this issue on a previous thread a while back and I think that the research and solutions they offered may be of assistance to you. Here’s a link to the post. I hope this helps!
