DualSense device recognized, but not inputs

[Tirsaan]

So I currently have a Dualsense connected to my Win10 PC, which works beautifully with most games and emulators. Steam has no issues, nor does Duckstation, Kega, Dolphin, etc. Now, normally I would chalk this issue up to PPSSPP's support being in development but...

I've seen multiple reports and tutorials of people successfully using their DualSense with PPSSPP. Even stranger, when I go to automapping, it recognizes it as a wireless controller alongside my wired arcade stick and (no longer connected) wired 360 controller. The automapping appears to be correct, but inputs from the controller aren't recognized. Both when loading a game, as well as trying to perform a manual mapping. Yes, the controller is on.

I had heard reports of Steam hijacking Bluetooth controller inputs, so I tried with Steam shut down, problem persists. Was curious if it was the controller, retried in Duckstation, no problem there. Tried directly connected with a USB-C connection, no go. I can also confirm the connection is stable as I previously used it for my Oculus.

What else could possibly be preventing or interrupting the Dualsense inputs from being recognized by SPECIFICALLY PPSSPP?
