FW13-AMD: Internal display never wakes up after a HDMI connection

On FW13 AMD, with Windows 11, up to date.
I’ve only installed the FW driver pack, not updated AMD to their own recent drivers (because then the IPC latency becomes too problematic, see my previous post).

I’ve now twice experienced the following problem, but I can’t consistently reproduce it:
I will connect the FW to my TV to play media with the VLC app, through a FW HDMI expansion card (AFAIK, v3).
The TV will be the main display in Windows.

When I unplug the HDMI cable (not having put the main display back to the FW monitor in Windows), the monitor never awakens, it stays black.

I tried to plug it back into the Thunderbolt 3-dock, which it’s plugged into most of the times, with dual monitors, network, etc; but that didn’t do anything.

I was able to connect a USB-ethernet adapter and tried to do login in with remote desktop. I could not connect via Win RDP, it never succeeded. I could connect via Parsec (virtual display driver is not installed BTW), but everything was extremely lagging. If I moved the mouse or typed something, it would take ca 10-20 seconds to react.
Task manager did not reveal anything hogging the CPU.
I’ve tried to reset the GPU driver with the “Ctrl Shift Win B” shortcut multiple times, but nothing happened.

And about 10 of these, with varying messages:

I could not figure out what the problem was. A reboot would solve it.
