“User-Declared Canonical” different from the actual “Canonical Tag

One of my website URLs https://www.tatahealth.com/online-doctor-consultation/general-physician stopped crawling today as Google decided to select a different canonical for it which isn’t even similar.

Also, my canonical tag is already implemented on the site & is not what is mentioned here.
This has severely affected my Google Rankings & site traffic.

Can anyone help me in resolving this issue as there are no guidelines anywhere on how to do so. Is this a bug or something?
