Kconfig GUI fails to open in VSCode on Linux and Windows

[_rm]

i am using vscode + nrf connect for vscode , nrf kconfig, ... on different machines, windows (11)  and linux (ubuntu current lts)

i often had the problem that nrf kconfig didn't open. now i tried to narrow it down.

i cloned the same projects in a workspace folder on a) windows and b) linux

i had tried some differently named builds but at the end only used "build"

on windows one of the projects in the workspace (2.6.0 / 2.6.0) allowed to open kconfig gui, but that didn't work for all projects -> kconfig gui can work on that machine

on linux none of the projects in the workspace (2.6.0 / 2.6.0) allowed to open kconfig gui, anyway kconfig gui worked on that machine in other workspaces -> kconfig gui can work on that machine

on linux:

 

on windows:

error looks the same on linux and windows

the vscode logs are not really helpfull. the only related info is :
