 Hi

 I tried using php 8.1 but i get a lot of deprecated messages with any of
 the default wp themes and a clean install with no plugins active.

 May i ask when wordpress is gonna support php 8.1?

 To see the warning message just goto any admin area. The one with the most
 warnings is the appearance -> themes page.

 Thank you for any feedback.
