Cannot Activate

I Love this plugin – working on a server with 10 WP Sites fine, PHP8.1.12

I just installed on a new server running PHP8.0 and the plugin will not activate. Here is the error I’m getting.

[28-Nov-2022 06:22:02 UTC] PHP Fatal error: Uncaught Error: Attempt to assign property "plugins" on bool in /sites/mydomain.com/files/wp-content/plugins/post-smtp/freemius/start.php:74
