php error when opening component

 Dear Support team

I have recnelty upgrade to Joomla 4 from version 3.10, and the upgrade was okay. The admin interface and the site are working just fine, but when using the Joomla 4 interface I visit Components > Router 66 > URLs i get this error message:

Deprecated: explode(): Passing null to parameter #2 ($string) of type string is deprecated in D:\domains\nazaudy.com\httpdocs\plugins\system\route66\lib\form\fields\route66pattern.php on line 79
