Thank you for reporting this bug. The error occurs when the forum has a duplicated “Add Groups to About” component.
We made a fix to consider the most recently updated settings and ignore older ones. It will probably be merged tomorrow.
In the meantime, until the fix is merged, if you would like to safely update your forum to the latest version, you need to disable the other “Add Groups to About” components and leave only one enabled before updating.
EDIT: Fix was merged, please let me know when update still causes issue
