Crashes Log ios EXC_CRASH

I have some problems with ios. Report a lot of bugs throughout the ios version. I use display.save to save and share a sceneGroup. Is this the problem?

Sorry for my bad English.

display.save( sceneGroup, { filename="Name.png", baseDir = system.CachesDirectory, isFullResolution = true, backgroundColor = { 1, 1, 1, 1 } } )
