Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
We have identified that with the recent update of the plugin the Russian language is not working as expected for the post-tests and we have reported the same to the dev team.
If you would like to downgrade the plugin temporarily you can downgrade by following this tutorial: https://rankmath.com/kb/version-control/
Thank you for your patience while our team solves the issue.
