I’m also unable to launch the Game with “Launch”.

Does this also happen in a new project?

If not, what have you done last before this occurred?

The error tells you, that you have tried to access a NULL variable. Have you added a variable of some objecttype that is used on begin play but not filled wiht an actual object?

Can you narrow down the Blueprint/Class where this happened?

No new projects work fine.

It’s hard to tell what I’ve done before because didn’t tried it for a long time.

To my knowing not.

Tried to disconnect all event begin plays and event ticks, still no luck.

These are the warnings and error I’m getting when I start up my project in the editor:

LogCollisionProfile:Warning: Profile (UI) - Custom Channel Name = ‘Weapon’ hasn’t been found

LogSlate:Warning: Failed to load font data from ‘…/…/…/Engine/Content/Slate/Fonts/Roboto-Italic.ttf’

Try refresh all nodes.
(I didn’t find any error whatsoever in this blueprint.)

LogUObjectGlobals:Warning: Failed to find object 'Class None.
(How do I find out where the engine is failing to access this Class?)

Hm,

the first Error says that you don’t have a Custom Channel name called “Weapon”. Maybe a typo?

The next error tells you, that the font can’t be found. Try using a different one or make sure that it’s in the mentioned folder.

And you may have a bugged Bleuprint. Check the asset that was mentioned and the blueprints using it.

You could try removing one actor by another from your scene and check if it keeps crashing. It is very hard to tell where the error sits like this :X

It just seems like one of your Blueprints is pretty broken :confused:

What I’ve done:

I was using the sample project for the Kinect Plugin and renamed it, all I did was adding assets and blueprints to it.
It always worked. I removed all my blueprints from the project and it’s still not working …

6

I got it working again it was not my fault! All I had to do was: Editor Preferences->Blueprint Editor->Save on Compile and set it to ‘Never’

Well, i’m glad you found the problem and solved it (: I will mark your question as resolved.
