Hello,
We released a quick Beta update you can try to see if that helps.
Please enable the Beta update by following this:

If you are unable to see an update, please clear Rank Math’s transients from:
WP Dashboard > Rank Math > Status & Tools > Database Tools > Remove Rank Math Transients > Remove transients

Please clear the caches, server, and WordPress after updating.
You can disable the Beta updates once you update to the latest version and if the issue is fixed.
