The error began to appear often:
Warning: CloudRecognizer.create callback: creating and destroying thread not match
UnityEngine.Debug:LogWarning(Object)
easyar.<>c:<GlobalInitialization>b__30_0(LogLevel, String) (at Assets/Plugins/_Assets/EasyAR/Core/Scripts/EasyARController.cs:51)
easyar.Detail:FunctorOfVoidFromLogLevelAndString_func(IntPtr, LogLevel, IntPtr, IntPtr&) (at Assets/Plugins/_Assets/EasyAR/Core/Scripts/csapi.cs:2957)
And the editor freezes after that.
