Thank you very much. We will consider upgrading to Drupal 9 as a main approach then.
We need to update MySQL 5.7.x to 8.x on our site and we use the Group module.
I searched for several related issues here but the comments are written in different years for various versions of Drupal and MySQL.
However, I found this one.

Does it mean that if I upgrade Drupal 8 to the latest minor version 8.9.20 I will not face the trouble with the Group module using MySQL 8.x?
Or should I apply a patch that was not committed to the core?
Of course, I will do various tests after MySQL upgrade, but I would like to be prepared.
Any information will be appreciated.
Thank you for providing the patch!
I need to test it in my project.
