A Native Collection has not been disposed, resulting in a memory leak. Allocated from:

This error message suggests that you have allocated some memory in your code using a native collection, but you have not properly disposed of it when you are done with it. This can lead to a memory leak, where the memory is not released even after your program has finished executing.

To fix this issue, you should make sure to dispose of any native collections that you allocate in your code. You can do this by calling the Dispose() method on the collection when you are done with it. For example:

NativeCollection<int> myCollection = new NativeCollection<int>(10, Allocator.Temp);
// Use the collection...
myCollection.Dispose();

By calling the Dispose() method, you are telling Unity to release the memory that was allocated for the collection. This will help prevent memory leaks and ensure that your program is using memory efficiently.
