Kubeconfig:
Hasn't changed since before the app crashes started
Additional context
Just upgraded the "bare metal" cluster with kubeadm to 1.20.0. Cluster came up healthy, opened Lens 4.0.0 everything seemed fine, all things look normal. After about 60 seconds, App crash

[cvandesande]

Lens just updated to 4.0.1 (Nice work with the AppImage updates on Linux).
Still crashes anywhere between 10-60 seconds of use.
ctrl-r (reload) is a good workaround.

Can confirm for Windows, Lens 4.0.1

Same here

same issue here.

[domrod]

Same issue using Lens 4.0.2 (on Debian buster).

I confirm that ctrl-r (reload) is a good workaround but crashes come later anyway.
On the other hand, when clicking on a cluster node, no additional information folder opens anymore also.
