PHP 8.4 Issues

[KyleStilkey]

I know it's probably not fully supported yet but there seems to be issues with this plugin on 8.4. 8.3 I receive no issues but on 8.4 sending emails seem to cause some major issues with WordPress to go into protective mode, and I notice the database entries for sending/received is empty.

Here is my crash logs.
