Joomla 4 login gives error

Joomla 3 site updated to Joomla 4 gives the following error after loging in with Google account:
ERROR 0 - Cannot access protected property Joomla\CMS\Menu\MenuItem::$params in /var/www/j4.queerspirit.net/components/com_jfbconnect/libraries/utilities.php:183

Any thoughts on why this is happening?  Thanks.

I have things set as follows:
Login with the SCLogin module. The settings for that are:
Login view settings:
Registration Component: JomSocial
Joomla Login Redirection URL: Main menu|Social (this is a menu item alias for JomSocial Frontpage menu item)

JFBConnect settings
New User Redirection: JomSocial menu item 'Edit profile'
Returning User Redirection: JomSocial Frontpage menu item

These settings work fine with J3 but give the error with J4. Interestingly I see the url of the error page is queerspirit.net/component/users/methods?...firsttime&Itemid=101 which is odd as I have logged in many times with that account!

Making the edit you suggested made no difference I'm afraid. In both cases same error and same trace:

The only one enabled is the Google one.

I have three enabled:

Open Graph - JomSocial
opengraph / jomsocial

Open Graph - Content
opengraph / content

Open Graph - Custom Object
opengraph / custom

I found that if I disable Open Graph - Custom Object then things work again. Not quite sure what that plugin is for? It was only enabled as it was like that under Joomla 3. 

Ah yes, seems I did have one set up which I had forgotten about! Disabling that allows things to work with the Open Graph - Custom Object enabled.
