TPA freezes on "Press to Start" screen

[mk47]

I did a fresh install of TPA via steam. My 4K playfield is in portrait mode, so I set the buffers on the DX11 config tab of TPA to 2160 and 3840 and selected "windowed". Then I added the PinballArcade11.exe path to the launch options in steam as usual to be able to launch the DX11 version in admin mode.
Now I can start TPA as Admin using DX11 without the FreeCamera Mod. But if I activate the mod before starting, TPA starts, the camera overlay is visible on the top right, but as soon as the words "Press to Start" appear, TPA freezes.
Any ideas?

A good example of rubber dug debugging ;-)
Just after posting the issue, I remembered to things: The buffer needs to be set to 4400 instead of 3840 and obviously the HighRes4K option needs to be set.
Now it works.
