I tried removing/adding photos while the device media picker is open, but couldn't get it to crash. I also tested a scenario when the device is empty.

Message:

NSRangeException: *** -[NSMutableIndexSet addIndexesInRange:]: Range {18446744073709551534, 1} exceeds maximum index value of NSNotFound - 1`

The likely explanation is that there is something wrong with this method or the way it is called:

- (NSInteger)adjustedIndexForIndex:(NSInteger)index forCount:(NSInteger)count
{
    if (self.ascendingOrdering) {
        return index;
    }

    // Adjust the index so items are returned in reverse order.
    // We do this, rather than specifying the sort order in PHFetchOptions,
    // to preserve the sort order of assets in the Photos app (only in reverse).
    return (count - 1) - index;
}

The value 18446744073709551534 may be the result of converting a negative value, such as -1, from NSInteger to NSUInteger that NSIndexSet works with.

---

I'm assigning a low priority because it happens extremely rarely.

The best solution would be to replace the custom picker with a native picker that supports search, filtering by favorites, and many other features.

This will be fixed in the scope of #21190

As expected – no occurrences since the 23.2 release. Closing.
