VS code does not show connected devices on Windows. This used to work before I upgraded to nRF Connect SDK v2.4.0. macOS works fine. The connected device is visible in my debugger and also in the nRF Programmer. I tried nRF9160dk, nRF52840dk, Thingy:91.
Could be related to the other issue from the screenshot, where build/mcuboot/child_image_preload.cmake is created with backslash '\' instead of forward slash '/' on line 7.
