Can't use PS4 controller for PS4 games on PS5?

We all know you can't use PS4 controllers on PS5 games. A few months ago I was playing with my (3rd party) PS4 controller and fight stick for PS4 just fine. But last night trying to play teenage mutant ninja turtles shredders revenge for PS4 on my PS5 we couldn't connect any of my PS4 controllers for multiplayer. Had to go out and buy extra PS5 controllers. Was there an update that stops me from using PS4 controllers if they're not first party? I tested them on other games and even no input on the menu.

They work on my PS4 and even pc just fine.

Pls anyone technologically inclined help
