multisite - plugins non in use showing errors

Hello to the dedicated support team!

Hope you are all doing well

I have a question about an issue with multisite.
Each sub-site had different themes with different plugins. On one of my sites, al posts show en error about a plugin that belongs to another template.

The sub-site doesn't allows me to deactivate the plugin on the specific sub-site.

How can I solve the problem? Or deactivate the plugin on this specific site?

The error: Fatal error: Call to undefined function atmb_get_field() in /home/katav225/public_html/wp-content/plugins/pojo-sharing/sharedaddy/sharing-service.php on line 518

Thanks!
