Thunderbolt controller initialization error

What this error means

Thunderbolt controller initialization error (THUNDERBOLT-CONTROLLER-ERROR) is a medium-severity fault affecting the motherboard. The Thunderbolt controller (Intel JHL series or AMD equivalent) fails to initialize properly. Thunderbolt ports show up as non-functional in Device Manager or are completely absent. This affects Thunderbolt 3 and Thunderbolt 4 docking stations, external GPUs (eGPUs), and high-speed storage enclosures connected to the TB port. It sometimes comes down to driver version mismatch. Follow the steps below to fix it.
