[Resolved] PHP 8.0 Compatibility Problem?

I am submitting a new topic after seeing my basic problem in another post here:
https://generatepress.com/forums/topic/php-8-compatibility/#post-2276959

I’m wondering if Generate Press is compatible with PHP 8.0? I just tried to update and an error and critical site error similar to what is on this page:

https://wordpress.org/support/topic/too-few-arguments-to-function-wp_widget__construct/

I just updated yesterday to WordPress 6.0 so maybe that wasn’t actually a good move.

I quickly downgraded from 8.0 to 7.4 again, and the site came back.

Note: I do have a Plugin called Featured Posts and “perhaps” this error is because of that?

Note: I have placed the word “USER” where the user directory name goes. I’m not sure if that matters, but thought I would anyway.

Here is the error from the error log provided to me by host at LiquidWeb

So here's what error log says about that error:
PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function WP_Widget::__construct(), 0 passed in /home/USER/public_html/wp-includes/class-wp-widget-factory.php on line 61 and at least 2 expected in /home/USER/public_html/wp-includes/class-wp-widget.php:162
