Thunderbolt 4 not working

Hello ,

I've recently purchased a lattepanda Sigma . I've received it and installed Arch on It . Thunderbolt 4 port didn't work .

After some days i reinstalled Windows 11 because i was thinking linux was the problem but Thunderbolt ports are not working either .

In bios thunderbolt is enabled.

Every other ports are working .

Any clues ?
