My Thunderbolt4 port is not working, how to verify that this is a hardware or OS problem?

I am using Fedora 38 on Lenovo ThinkPad P1 Gen 4. Kernel version is 6.3.11. It seems that my Thunderbolt 4 ports are powered on, but whatever I plug to them I get no output. Is there any way to verify that this is due to hardware or lack of support in the operating system? ### More background The port used to work, which is why I am suspecting a hardware failure. I used to connect Lenovo dock to it, but one day it just stopped working. Here are some commands I used to check the port is still seen by the OS:

boltctl list -a

The dock is the only T4 device I have and I get a blank output from boltctl list if I plug it in. I also tried plugging a standard USB-C pendrive and that doesn’t get detected either. Running journalctl -u bolt gives me:

Please let me know if you have any suggestions of what else can I run to investigate the problem.
