5700XT + Sonnet eGFX Breakaway Box 550 + Lenovo T14 Gen1

Before buying everything I needed for this project I checked the compatibilites and everything should be okay.

After installing all Windows Updates, all driver for the T14 including Thunderbolt and the Radeon driver I should technically be good to go.

When I turn on the laptop with the eGPU already plugged in, everything is fine in Windows and I get all the power.

The problem is when I disconnect it and try to reconnect it or just connecting the Thunderbolt cable after boot doesnt work.

Radeon Software gives me the error: "No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for your AMD hardware."

Thunderbolt Control Center sees the Sonnet Box but in Device Manager, the AMD Radeon RX 5700 XT has warning icon on it.

Does anyone know how to fix that?

Thank you
