Error While Preview On both Local & Device

I am getting the following error while running preview on both local and device , but only local preview works fine.

[Viewport]: System.ExecutionEngineException: SIGILL

My current Fusetools version is 0.37 , Using iMac with OS macOS Sierra, and Device is Android phone with Android version 6.0 Marshmallow.

Hi seddiq,

exactly what is the Android device? A brand name and model number would be nice. And which Fuse 0.37 build number are you on?

Could you also happen to have a minimal reproduction which results in this error that you could share? From the looks of it, the problem might be related to some Observable function (FunctionMirror hints at that), but there’s no telling without seeing some code that triggers the error.

Hi Uldis, Thanks for Reply
Android Device is " LeTV Le 2" a chines brand model number (le X620), Fuse 0.37.0 (build 12978) , I have a MapView a long side of other Panels , With a popUp , I think the popUp part is creating this problem, Because an Observable for checking the condition.

Thanks, but can we see the code?
