Hello, when I downloaded version 5.0.3, I was aware of the risks of working with Joomla 6. In the end, for your module to work on Joomla 6, you need to do the following: replace line 28 in the file at src/Helper/ResponsiveGridForArticlesHelper.php from use Joomla\CMS\Filesystem\Folder; to use Joomla\Filesystem\Folder;
Everything seems to be working correctly now, but if there's anything else that needs to be added, please let me know. All the best!
