Page Not Found

A single category page is not working for me. For example, we have this category here – https://prnt.sc/NexSsmt3dW_a, but going to this page https://theisland360.com/listing-category/fitness-activity-and-instruction/ says, “Page not found”.

All the pages are setup with shortcodes here – https://prnt.sc/5TfyNhd1Muol

I have flashed the permalinks several times, but it did not resolve my issue.

Please help.
