nRF Connect SDK Tutorial - Part 2 | 3.2 Set it up - light_controller not working VS Code

Hello everyone and hello kindly nRF support team!!

One question again sry. I am using SDK 1.9.1 through VS Code and working on the nRF Connect SDK Tutorial - Part 2 - 3.2 light_controller example.

https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-2-ncs-v1-4-0

When I try to build and flash the self created project light_controller, described in the tutorial I get the error seen in the terminal

Sry for the bad input, is ther a better way to show the output of my error?

Okay so I tried to downgrade (SDK tag v1.4.0) my SDK like describend in the same tutorial 

https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-2-ncs-v1-4-0

through command prompt git checkout v1.4.0 and west upgrade , afterwards downloaded the sdk, because the tutorial was written at the time of this SDK version

I dont know if everything is right selected in the build setup now for sdk v1.4.0 becaus there are nrf5340df or nrf5340pdk boards available.

still same errors

Hello_world project and everything before the turorial was working.

Thank you for your help,

Christoph
