get_current_screen() called outside admin context causing fatal error on API

Hi,

We're experiencing a fatal error caused by the payment-forms-for-paystack plugin
calling get_current_screen() in class-forms-update.php at line 602 via the
save_post hook.

This function only exists in the wp-admin context. When WordPress REST API
requests trigger save_post (e.g. creating or updating posts programmatically),
get_current_screen() is unavailable, causing an uncaught fatal error that crashes
the entire site.

Full error:
Uncaught Error: Call to undefined function
paystack\payment_forms\get_current_screen() in
/wp-content/plugins/payment-forms-for-paystack/includes/classes/class-forms-update.php:602

The fix is straightforward — wrap the get_current_screen() call with a context
check:

if (!function_exists('get_current_screen') || !is_admin()) {
return;
}
$screen = get_current_screen();

This prevents the function from running outside wp-admin while preserving all
existing functionality within the admin interface.

Could you please apply this fix in the next plugin update? As a temporary
workaround we have added a custom plugin that removes the save_post hook during
REST API requests, but this causes post previews to break.

WordPress version: latest
Plugin version: current (no updates available)

Thank you.
