Oppo A12 asking for passcode when attempting to hard reset via ColorOS 6 recovery

Question

I completely forgot the passcode to my Oppo A12, so have resorted to a hard reset. The issue is that I cannot hard reset either, as if I enter recovery mode and try to wipe the phone's data, the phone yet again requests for a passcode. I do not know the passcode and therefore can't even reset my phone via recovery. Is my phone just bricked at this point? I am on Android 9 and ColorOS 6.1.2.
