When I check the Tools -> Site Health I see two issues from the staging site that are not in the original site:
#1 A scheduled event has failed Performance
The scheduled event, action_scheduler_run_queue, failed to run. Your site still works, but this may indicate that scheduling posts or automated updates may not work as intended.
#2 The REST API encountered an unexpected result Performance
The REST API is one way that WordPress and other applications communicate with the server. For example, the block editor screen relies on the REST API to display and save your posts and pages.
When testing the REST API, an unexpected result was returned:
REST API Endpoint: https://mydomain.com/stage/wp-json/wp/v2/types/post?context=edit
REST API Response: (500) Internal Server Error

About the not working REST Api, try to
