Critical error after updating PHP

 I updated my PHP through Hostgator, and now I get a white screen saying there is a critical error. I clicked the WordPress “recovery mode” link in the email that I got, but that also takes me to the white screen. The email says that there is an error from the Job-Manager plugin.

I am on WordPress version 6.8.3. Active theme Local Business Pro (version 2.0.1), the plugin with the issue is Job Manager (version 0.7.25), PHP version 8.3.12.

Here are the error details from the email that I received:
