I'm experiencing an issue with custom post types created using Meta Box on my WordPress site. While the custom post types display correctly on the frontend, I cannot edit them. When attempting to edit, I receive the error message: "You attempted to edit an item that doesn't exist. Perhaps it was deleted?"
Here's a link to the CPT archive page:

And here's one of the CPTs:

Technical Details:
Custom post types were created using Meta Box
Posts are visible and functioning correctly on the frontend
Error occurs only when trying to edit in admin dashboard
Posts have not been deleted (confirmed by frontend visibility)
Troubleshooting Steps Attempted:
I have resaved permalinks a dozen times or more.
I increased max_input_vars to 100000.
Could this be related to a recent plugin update, permalink structure issue, or database problem? Any assistance in resolving this would be greatly appreciated.
