Building errors-cannot open file '\/da1458x_config_basic.h'

Dear Dialog,

Recently I met a strange building error. This occurred after I adding the BLE_SDK6_examples following the tutorial on this page GitHub - dialog-semiconductor/BLE_SDK6_examples: Examples for the Dialog Smartbond Bluetooth low energy families based on the SDK6

I tried the lasted SDK version and the SDK SDK_6.0.18.1182.1. As long as I building the examples in the ble_examples folder, the errors will be as shown below:

But there is no error after I building the examples in the peripheral_examples folder. It seems that the errors only occur when I build the examples including the BLE part.

Could you please help to resolve this problem. Thanks a lot!
