Crash when opening settings panel after a first fresh install #1782
Description
Describe the bug
I installed Radar Desktop on Windows for the first time using scoop (using a regular console, not an admin). Then I open the UI, click on settings and it crashes.
To reproduce
Open Radar Desktop and click on settings. I tried rebooting my machine, without any difference. I also tried copying the folder %USERPROFILE%/.kube containing setup config from a colleague that does not have the issue but still, no difference and the Kubernetes machines are not yet seen in the tool
Expected behavior

Thanks for the report, and for including the diagnostics. Reproduced: when Radar Desktop starts without a usable kubeconfig, opening Settings hit a nil-pointer crash in the Prometheus auto-discovery path on the Go side, so it's nothing about your machine or the scoop install. Fix is in #1787 and will be in v1.14, which is going out in the next few minutes.
On the copied kubeconfig: the diagnostics still show zero contexts loaded, so Radar isn't finding it. On Windows it reads
%USERPROFILE%\.kube\config(the file, not just the folder) unlessKUBECONFIGis set. Once v1.14 is installed, the Connection section in Settings will also let you point it at a file directly.TristofCuber commentedon Sep 16, 2026
Great, I'm impressed with the speed at which this was solved. Thanks a lot!
fix(desktop): don't crash when Prometheus discovery runs without a ku…
