Application crash on windows phone (Lumia 650)

I use WebCamTexture and a RowImage to start camera to take screenshot in my application. In start I create an new webCamTexture and a rowImage where mainTexture of rowImage send to webcamText, and Play.
When I want to go to another view I stop camera. If I want to take another screenshot my application stop, crash, exit and give me some error . Any ideea why happening that? and any solution to solve ?

Error: Operation has failed with error 0x8007000e: Not enough storage is available to complete this operation.
(C:\buildslave\unity\build\PlatformDependent/MetroPlayer/MetroWebCamTexture.cpp:WebCamTexture::Update at 582)

I remember WebCamTexture to be leaky on Windows Store, calling Play() & Pause() multiple times used to increate memory usage.
What I don’t understand is what does webcam have to do with taking screenshots?

Can I reduce memory when I call Play() & Stop()?.. I use webCam to save a picture. How to save a picture (take screenshot) from a camera in game? - Questions & Answers - Unity Discussions

If you only want to take picture using phones camera, I think it’s better to use native API for that

I try to do with that but give me some errors. Therefore I used WebCamTexture .But problem I think is not when take screenshot. When try navigate in X and Y view multiple times includes stop and play camera, crash my aplication…

Can you type the same code in MainPage.xaml.cs?
In Unity scripts you have to wrap such code behind appropriate defines, because it’s not compatible with editor.

No can’t write in MainPage.xaml.cs . Is any way to reduce memory when start and stop camera?
