1. Server resources: Sometimes, if your server resources are limited, it can cause issues with updating the database. Consider upgrading your hosting plan or contacting your hosting provider to see if there are any server-side issues causing the problem.
2. WordPress core files: If none of the above solutions work, it’s possible that there might be an issue with your WordPress core files. Try re-uploading the wp-admin and wp-includes folders from a fresh WordPress installation.

If none of these solutions work, you might want to reach out to your hosting provider’s support team or seek assistance from the WordPress community forums for further help and troubleshooting.
