How do I make multible levels with one hud?

Hi Folks. I have build a very simple game structure, to test the level system of my next game project. And I'm struggeling at the first steps...

There are 3 Layouts:

- Layout 1 startmenu

- Layout 2 Level 1

- Layout 3 Level 2

Objects and Vars:

- only one variable "level"

- only one text object to show this variabe

- 3 Buttons to click through the layouts, just for testing the changing of the layouts

And it doesn't work... Error Code in the Browser: STATUS_ACCESS_VIOLATION

The project is so simple, and don't work... can anybody help me? What went wrong?

Here is the File: LINK

I put the .c3p file into a folder on GoogleDrive:

The layer that the HUD is on, set the Global to Yes.

Then, add an empty layer to all other layouts and call it the same name.

Thanks for your usefull hint.

I did it that way, and it works - sometimes...

Maybe the Problem is elsewere...

If I start this Mini Project File in the Preview, sometimes it works, and sometimes not... From 10 attemts to preview the project, 5 are working, and 5 fail... Error: STATUS_ACCESS_VIOLATION

Curious...

Somemody an idea?

I just checked th preview debugging mode, and in this mode it works every start:
