Hello,
I have exactly the same problem as described by user almartin21 on Oct 23, 2022. Unfortunately, the solution has not been published.
The installation of "Guru Pro" 6.1.0 generates the error message "1364 field 'review' doesn't have a default value". In the backend, a configuration of "Guru Pro" is not possible because there are always error messages when trying to save.
I use Joomla 4.2.6
