Some SDK are missing when creating a build configuration

Hello,

I have recently been working on other Zephyr projects that use non-Nordic MCUs. I installed raw Zephyr in my documents folder (“C:\Users\gilles.devillers.SECTRONIC\zephyr”). Now, when I’m trying to build my older nRF projects, it didn’t work, showing weird error messages about colliding Python versions. I deleted my build configurations, but now I can’t create a new one: the SDK list only shows Zephyr, but not the installed ncs ones anymore:

But when exporting the debug information from the VSCode extension, the SDK are all listed:

How can I repair my development environment so that the VSCode extension properly shows all my installed SDKs?

Thanks.
