Describe the bug
I'm encountering two critical errors when attempting to save a post in WordPress using the Rank Math plugin. These errors prevent the post from being saved and cause a crash.

To Reproduce

1. Log into the WordPress admin panel.
2. Open an existing post or create a new one.
3. Edit the post and try to save it.
4. A fatal error occurs, preventing the post from being saved.

Expected behavior
After making edits to the post, I expect the post to save successfully without any errors.

**Additional details on server **

• PHP Version: 8.0
• WordPress Version: 6.3.1
• Rank Math Version: 1.0.203

IMPORTANT:
I managed to resolve the bug, and here's the patch in git format for version 1.0.203. However, I'm primarily not a PHP developer, so I would greatly appreciate if you could review my solution. solve issue.zip
