ASRock X570 Taicihi + Alpine Ridge 2.0 Thunderbolt

   Hello,
My Thunderbolt Expansion card begins not to work. I guess this happened after Windows updates.
It was working flawlessly for a long time with no issue.

Motherboard: ASRock X570 Taichi
BIOS: Latest 4.60 version. "Thunderbolt" is enabled with "No Security" in BIOS preferences.
Thunderbolt Expansion Card: Gigabyte Alpine Ridge 2.0
The device I want to run: Apple Thunderbolt Display 27"
OS: Windows 11 with latest updates.
GPU: Nvidia RTX 3080 Ti

Simply the Thunderbolt Expansion Card is not working now.
I tried to install almost all TB3 drivers I can find, but none of them helps now. Drivers I tried so far:
- Legacy 16.2.52.250
- Legacy 17.4.79.510
- 1.41.1030.0
- 1.41.1054.0
- 1.41.1094 (says latest)
To mention, the driver Gigabyte offers on the website for Alpine Ridge is extremely old (16.2.52.250).

This is the story of what happened:
- First, the Apple Thunderbolt Display monitor started not to work suddenly. There is nothing wrong with the monitor, it still works with a Mac. I think it happened after the latest Windows 10 updates. I tried to reset the PC by removing everything and reinstalling a fresh Windows 10, nothing changed.
- Later I installed Windows 11 and installed the Thunderbolt driver. A strange thing happened, the monitor started to work sometimes but not always. When I start the PC, it sometimes worked and sometimes didn't work. So the rig is (mobo - expansion card - OS - display monitor) still able to work but something is preventing it.
- I manually updated the related TB and Display drivers in the "Device Manager" tab. I was aiming to overcome this instability.
- Now it is not working at all. I tried all of the drivers I mentioned above. Unplugged and plugged the card and device. Reboot. Restart the PC again by removing everything and making a fresh install. Not working.

What shall I do to troubleshoot this case?
