Metrics are not available due to missing or invalid Prometheus configuration.

Describe the bug
We have installed kube-prometheus-stack 58.2.2 with flux. All pods are fine:

We already applied the values described here: https://github.com/lensapp/lens/blob/master/troubleshooting/custom-prometheus.md but the cluster node metrics are not available. Further, the memory metrics are not correct (see screenshot below)

However pod metrics are working.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
To be able to see node metrics as well.

Environment (please complete the following information):

• Lens Version: 6.5.2-366
• OS: Ubuntu 22.04
• Installation method (e.g. snap or AppImage in Linux): deb

Logs:
When you run the application executable from command line you will see some logging output. Please paste them here:

when starting open-lens in CLI the app doesn't outputs any logs

Kubeconfig:
Quite often the problems are caused by malformed kubeconfig which the application tries to load. Please share your kubeconfig, remember to remove any secret and sensitive information.

kubeconfig works fine
