I reduced the speed of the SDcard to 400kHz and mounted it on a nucleo board. Still did not do it on the custom board. I now have the feeling something is not right with the custom board.

The code fails only after :-

 if (HAL_SD_Init(&hsd) != HAL_OK)
 {
 Error_Handler();
 }
It fails in the HAL_SD_Init() only even after changing to 1B.

So your hardware is not working .

What board : custom or nucleo ...?

Length of tracks cpu -- sdcard ?

+

try simple setup for beginning with sd-card:

- 1 bit mode

- no dma template

- port/pins : all on speed: medium + pullup on
