Conflict with Co-Authors Plus plugin (Fatal error)

Hi there,

I’m getting below Fatal error when the plugin: ‘Co-Authors plus’ – https://en-gb.www.ads-software.com/plugins/co-authors-plus/ is activated.

Both plugins – Web Stories and Co-Authors Plus were working fine till this error came up. Upon disabling each plugin one by one, the issue narrowed down to Co-Authors Plus.

Error as shown below:

Fatal error: Uncaught Error: Return value of Google\Web_Stories\REST_API\Stories_Users_Controller::user_posts_count_public() must be of the type string, int returned
in /wp-content/plugins/web-stories/includes/REST_API/Stories_Users_Controller.php on line 262

We tried re-creating the issue on a new site but we couldn’t reproduce this issue.

Can you help let us know how we can also run Co-Authors plugin.

p.s.: we disabled co-authors and instead also tried: ‘PublishPress Authors’ – https://www.ads-software.com/plugins/publishpress-authors/ but even that plugin threw the same above arrow. You help will be highly appreciated.
