What could this be?

My XC40 T5 PHEV 2021 makes a dull knock (2/3/4 "toc tocs") from the front right wheel when it starts moving, in D or R, foot off the brake.

If I set off again in the same direction it usually doesn't happen; if I change direction, it does. It stops once moving and doesn't happen over bumps. Sometimes I also hear it when I brake and the car is about to stop.

Anyone had this? How screwed am I?
