My LattePanda Sigma Thunderbolt 4 ports no longer recognize anything plugged in to them. The thunderbolt controllers are recognized in windows 11, just cannot use eGPU (Razer Core X w/ Radeon 6800) any usb-c power supply (meets req of sigma), thunderbolt 3 SSD or usb-c SSD. All of these things work on my 3 other thunderbolt PCs as well as my macbook pro (last intel one).
