Magento 2.4.5 issue after Upgrade with PHP 8.1

[anurac01no72df]

After Upgrade to EE 2.4.5 with PHP 8.1 i am facing many default php function issues like 

 1- Blank Parameter should be a part of __construct

 2- Function Parameter Without Variable Type should not be passed as a null

 3- Deprecated Functionality: explode(): Passing null to parameter #2 ($string) of type string is deprecated

I am using Windows 10 with WAMP 3.2.6 with PHP 8.1.

Please suggest what changes i need to do?
