you got fault addr 0xc, r3 00000000, not same case.

in case, happens when there no objects rendered on camera, , camera.targettexture has been set arendertexture, destroy(arendertexture) crash.

fix code 1 (not recommend works):

destroy(arendertexture, 1.0f) 

fix code 2 (maybe better way, attach follow script on crashed camera):

using unityengine;  [requirecomponent (typeof (camera))] public class crashfix : monobehaviour {     void awake () {         camera _cam = gameobject.getcomponent<camera>();         gameobject _invisibleobj = gameobject.createprimitive(primitivetype.quad);          _invisibleobj.name = "crashfix";         _invisibleobj.layer = getfirstlayernumberfrommask(_cam.cullingmask);         _invisibleobj.transform.parent = gameobject.transform;         _invisibleobj.transform.localscale = new vector3(0.001f, 0.001f, 0.001f);         _invisibleobj.transform.position =             _cam.transform.position + _cam.transform.forward * (_cam.nearclipplane+_cam.farclipplane)/2f;          material _mat = new material(shader.find("ui/default"));         _mat.color = new color32(0,0,0,0);          var mr = _invisibleobj.getcomponent<meshrenderer>();         mr.sharedmaterial = _mat;          destroy(_invisibleobj.getcomponent<collider>());     }      private int getfirstlayernumberfrommask(int mask)     {         if (mask == 0) return 0;          int result = 0;         while(true){             if ((mask & 1) == 1) return result;              mask >>= 1;             ++result;         }     } }
