Oh… Sorry. i found what was the issue.  
I didn’t have stable internet last week and tried to play the editor. so i clicked some options in setup and so on. So what i’ve done is check **Custom application** in **Defold Preferences**. Now i unchecked it and everything become works.

regarding **Unhandled event loop exception** i followed [this solution](https://forum.defold.com/t/error-when-i-press-open-project-linux-32-bit-solved/923/12) Installed [XULRunner](https://developer.mozilla.org/en-US/docs/Archive/Mozilla/XULRunner/1.9) and added

> -Dorg.eclipse.swt.browser.XULRunnerPath=/Library/Frameworks/XUL.framework

to the _Defold.app/Contents/MacOS/Defold.ini_ file
