Cannot open source files

Hello,

I'm struggling a lot right now. I tried to open different examples found on the NRF5 SDK. But all of them showed me the following problem:

It looks like none of the header files can be open. I'm on professional Windows 10.

I tried to follow these two thread:

 Problems with VS Code 

 Problem getting started making a build configuration in nrf Connect Extension for VS code 

But none of their solutions seemed to solve my issue.

I use VS thanks to the nRF Connect for Desktop. I downloaded everything following the steps showed in the Youtube videos.

The next document is the support informations generated thanks to the "Generate Support information" command.

I also tried to delete Connect Sdk and dowload it back again but it didn't work. I also checked all the possible solutions gathered on this page:

devzone.nordicsemi.com/.../nrf-connect-sdk-build-fails

I really don't know what to do next...
