Unable to get ESP32 devboard with GC9A01 display and SDcard reader to work

[vultureonline]

I have this ESP32 devboard with a GC9A01 display and SDcard reader that I want to get to work with the TFT_eSPI library.
In fact, I got this to work earlier but I changed laptops and had to install the Arduino software and TFT_eSPI library again (and lost the former configuration).
Now I'm banging my head in getting this to work.
The display works and the SDcard works when I use them seperately but when I use them together in one program, the SDcard stops working right after the tft.init(); command.
The old compiled code still works fine but I cannot get it to work anymore from the Arduino sourcecode.
It must have to do something with the newer version of the libraries or Arduino environment or the (lost) configuration of the TFT_eSPI config files but I think I tried everything and nothing works...
I even tried the example of the TFT_eSPI library that reads the jpg-images from SD. That also fails to initialize the SDcard reader.
Anyone has an idea what I might be doing wrong?

Never mind my post.
I already found the solution to this.

I added the following line to the 'setup200_GC9A01.h' file:
#define TFT_MISO 2
With that it defines the SPI bus with the right pins so the SD cardreader (that is on the same bus) will still work when the TFT-drivers are initialized.
