Fatal error message when activating plugin other than Otter

[rodica-andronache]

Description

When you have Neve FSE, and try to activate another plugin other than Otter, you get this message "Plugin could not be activated because it triggered a fatal error."

Step-by-step reproduction instructions

1. Install Neve FSE
2. Try to install and activate a plugin, other than Otter -> the message "Plugin could not be activated because it triggered a fatal error." appears even though the plugin gets activated.

The user suggested to change this:

add_action( 'activated_plugin', 'after_otter_activation' );

to:
add_action( 'activated_plugin', array( $this, 'after_otter_activation' ) );
