Hi there!
Due to some unavoidable circumstances, I was unable to look into the issue, sorry for this.
The version upgrade may have an issue I guess. This is why I have taken a full backup of your site and then tried to completely remove the Template and then reinstall to see if it helps!
I am trying to restore the last backed up version but it is showing me an error:

Where are your backups stores actually? Can you restore the backup for me kindly? It seems I am not authorized to do so from here.
Please let me know once it is restored.
Best Regards
