Loading TMXTiledMap problem (cocos2d-x vers. 3-4) [SOLVED]

cocos2d-x C++
1

HI,
today trying use TMXTiledMap but obtain a runtime error

cocos2d-x debug info(10067): cocos2d: fullPathForFilename: No file found at lab.PNG. Possible missing file.

All file is present in directory Resources don’t understand where is the problem.
IF using Tiled editor the level is loading correctly.
Another strange problem is :
if I remove the code for loading the tile-map the application continue to crash with the same errore “No file found at lab.PNG. Possible missing file.”
Same if uninstall the app from my android phone, Clear project and rebuild.

TMXTiledMap *map=TMXTiledMap::create("Level/Level6logic.tmx");
this->addChild(map,99);

Now the code work. The problem is that i remove a comment on other part of my code …that produce segment fault.
Strange behavior of logcat that presents the same problem even if clear the log file.
