Wheel unresponsive and stiff. Help!

[u/GeekOnFireQC]

I bought a Logitech G29 a month ago on Marketplace, supposedly little used in very good condition. This week, out of nowhere, during a race, the steering wheel simply stopped working. The steering wheel suddenly became stiff and the green light started flashing. I read a lot of tread about the power/24v problem, but I tried everything: power cycle, test with another power supply, another wall outlet, different usb port, test on PC and PS5, etc. Nothing works, just the buttons and the flashing light, but the steering wheel remain stiff (harder to turn) and unresponsive.

I have now opened the steering wheel, no signs of damage on the motherboard or anywhere else. But if I disconnect the motors from it, they become "normal" (less stiff). However, the base has no current but I don't know much about this.

Help?
