CS0266 cannot convert type 'object' (which actually is a argument of type int[,]) to 'int[,]'

Hello everyone! i've got a bit of a struggle with the following function:

 int[,] SmoothMap(int[,] map, int amount){
         int[,] TempMap = map.Clone ();
         for (int StupidVar=0; StupidVar<amount; StupidVar++){
 
             for (int x = 0; x < LevelSize; x++) {
                 for (int y = 0; x < LevelSize; y++){
                     Delidding(map, x, y);
                 }
             }
 
 
         }
         return TempMap;
     }

Unity throws out the error for line 2

error CS0266: Cannot implicitly convert type `object' to `int[,]'. An explicit conversion exists (are you missing a cast?)

It thinks that the argument is not off type int['], but of type 'object'. How can i fix this?
