What means SecTaskLoadEntlitlements failed error=22
You need a bit of introduction to understand what SecTaskLoadEntitlements really is/does:

An application (.app) in OS X is really a folder containing a number of files, including the actual program, resources (graphics, sounds, etc) as well as system files such as plist files.

One of these plist files contains a descriptions of the application's entitlements. An entitlement is either that the application "can do" a certain thing, or that it has permission to do a certain thing.

Examples on OS X would be for an app to have the permission to get read-only access to your Music folder, or that it is allowed to interact with Bluetooth devices, record from your microphone, etc.

Application on the OS X App Store are required to use entitlements in so that that they're required to be sandboxed, which is an entitlement in itself.

In order to make sure that entitlements cannot be changed or unrightfully gained, the entitlements are "signed". This means that the developer of the application uses a specific cryptographic key to "sign" the entitlements.

OS X checks the signature when loading in new applications, and only if it is signed correctly will it load the entitlements and apply them to the program.

Your error message means that the "launchd" program tried to load in the entitlements for an application, but it failed with error number 22. The number 22 means that an invalid argument (parameter) was given.

This completes the explanation of what SecTaskLoadEntitlements is.

To answer your main question you need to know what launchd is. Launchd in general is the first program started when you boot OS X - it has process identifier number 1. Its job is to start all the other programs necessary for booting your computer. It can also start programs based on time and events, such as for example hardware changes.

Therefore the log messages you see are not necessarily linked to the problem you're having. Launchd is running continually no matter if you're playing the game or not. There is no indication that the log messages relate to your game as per the information you have given. It is thus unlikely that the problem with your game has anything to do with SecTaskLoadEntitlements.

I would write a message to the Dread Out support to ask for a fix.
