Start the gui with custom java command to allow more ram usage.
If that still doesn't solve it, the input file might contain a zip-bomb, create a copy of the input file and remove zip-bomb with 7zip or so and then try the deobfuscator.

how i can start with custom java command?

[Janmm14]

1. Open console / bash / cmd
2. Use java command with custom max ram argument and the jar argument to start deobfuscator-gui.

Google is a good way to find out details, but if you don't know these yet, I'm afraid this deobfuscator probably won't help you much anyway.
