EFM8BB3 SLSTK2022A Microcontroller SPI Software Example

I need someone who has worked with this microcontroller from silicon labs before. This project is a really simple project as simplicity studio 4 have Software Examples and I want to implement a certain Example. I have two boards „EFM8BB3 SLSTK2022A busy bee board“. One will be flashed with SPI Master Example (Getting Started > Software Examples > SPI > EFM8BB3 SPI Master), the other one with SPI Slave Example (Getting Started > Software Examples > SPI > EFM8BB3 SPI Slave). I have tried the examples and they don‘t seem to work correctly on my boards. I need someone to fix this on my local machine (using Team Viewer for example) and I will show you the board setup. Only money will be paid, if you manage to fix this on my local machine and I managed to get the SPI example to work as expected!
