Error within tableview when cells are switching sections - ios

Question

So in my table view, I have an array called dataArray and it's getting its objects from a server using JSON. I added a button to each cell and when the button is clicked the cell is supposed to move to another section/ or another array called followedArray to be more exact. Now the cells are transferring to the other section but after moving 6 cells I get an error that saids this. All arrays are NSMutableArray. Also, I'm new to iOS so try to work with me, thank you.

Side note, I can make a separate error post but I have another issue, the images displaying in the cells are being changed to other images when switching sections, using the pod SDWebImage.

This is what helped me fix the errors I was having. Credits to #AliOmari for helping me out.
In cellForRowAtIndexPath
// Configuring the cell
Data * dataObject;
if (!isFiltered) {
if (indexPath.section == 0) {
dataObject = [followedArray objectAtIndex:indexPath.row];
[cell populateCell:dataObject isFollowed:YES indexPath:indexPath parentView:self];
}
else if (indexPath.section == 1) {
dataObject = [dataArray objectAtIndex:indexPath.row];
[cell populateCell:dataObject isFollowed:NO indexPath:indexPath parentView:self];
}
}
else {
dataObject = [filteredArray objectAtIndex:indexPath.row];
[cell populateCell:dataObject isFollowed:NO indexPath:indexPath parentView:self];
}
return cell;
Inside my Button
[self.myTableView beginUpdates];
// ----- Inserting Cell to Section 0 -----
[followedArray insertObject:[dataArray objectAtIndex:indexPath.row] atIndex:0];
[myTableView insertRowsAtIndexPaths:#[[NSIndexPath indexPathForRow:0 inSection:0]] withRowAnimation:UITableViewRowAnimationFade];
//NSLog(#"indexPath.row = %ld", (long)indexPath.row);
// ----- Removing Cell from Section 1 -----
[dataArray removeObjectAtIndex:indexPath.row];
NSInteger rowToRemove = indexPath.row;
[self.myTableView deleteRowsAtIndexPaths:[NSMutableArray arrayWithObjects:[NSIndexPath indexPathForRow:rowToRemove inSection:1], nil] withRowAnimation:YES];
//NSLog(#"Array =%#",followedArray);
[self.myTableView endUpdates];
