Thanks for hanging with me here.
Specs:
Windows 10 Pro v22H2
Intel i9-7900x 3.3 GHz
32 GB RAM
Radeon RX Vega GPU
Default projects in 5.2.1 which are also not accepting input out of the box: Third Person Template, First Person Template, Top-Down Template.
This is both with and without the gamepad connected.
Not using DS4Windows or Joypadder
Yes, in all projects Input → Default Classes have both options set to Enhanced.
I added the node structure you suggested above to the SportsCar_Pawn Event Graph, and no, pressing the keys when in Play mode does not print the strings to the editor.
