ArgumentOutOfRangeException Index was out of range Must be non-negative and less than the size of the collectionParameter name indexSystemThrowHelperThrowArgumentOutOfRangeException SystemExceptionArg

This error message indicates that an argument was passed to a method that is outside the valid range. In this case, the index parameter is expected to be a non-negative value and less than the size of the collection, but it is not meeting these conditions.

The problem is likely occurring in the line of code that tries to access an element in a collection using an index. The code is trying to access the item at the given index, but the index is either negative or greater than or equal to the size of the collection.

To resolve this issue, you should check the code where the index is being used and ensure that it is within the valid range. You may need to review the logic that determines the index value and make sure it is calculated correctly. Additionally, you should also check if the collection is empty before trying to access any elements
