Theme Conflict

It appears that the June 1 update to RankMath has caused a conflict with the Divi theme by Elegant Themes. Now when I try to save changes made using the Divi Visual Builder, I get the following error:

An error has occurred while saving your page. Various problems can cause a save to fail, such as a lack of server resources, firewall blockages, plugin conflicts or server misconfiguration. You can try saving again by clicking Try Again, or you can download a backup of your unsaved page by clicking Download Backup. Backups can be restored using the portability system while next editing your page.

Contacting your host and asking them to increase the following PHP variables may help: memory_limit, max_execution_time, upload_max_filesize, post_max_size, max_input_time, max_input_vars. In addition, auditing your firewall error log (such as ModSecurity) may reveal false positives that are preventing saves from completing.

Lastly, it is recommended that you temporarily disable all WordPress plugins and browser extensions and try to save again to determine if something is causing a conflict.

To troubleshoot, I disabled all plugins, which resolved the save error. I then reactivated plugins until the error recurred, which happened when I reactivated RankMath. To be sure, I deactivated RankMath again, activated all other plugins, and was able to save without error. I then reactivated RankMath and the error recurred. I had not experienced this error until today. There have been no Divi updates since May 12 so I am reasonably certain it is not my most recent Divi update that caused the problem and that it is rather related to the most recent RankMath update. I will also report this error to Elegant Themes but would appreciate RankMath support to troubleshoot and resolve.
