Issue With PHP 8.3

I’ve updated a client site of ours to PHP 8.3 from 7.4 and now I’m getting the below error. I tried on another client who runs a different theme and I get the same thing. I’ve tried deactivating all other plugins but I still get the error.

WordPress 6.8
Yoast 24.9

error_log entry:
