Internet blocked due to k3s

[iirekm]

• I've installed k3s yesterday using the curl method, without any custom parameters, in the beginning everything worked fine
• Few hours later, internet stopped working, sudo systemctl restart NetworkManager didn't help, neither logout and login, only full OS restart helped
• When I've stopped k3s (sudo systemctl stop k3s) to save laptop battery, internet stopped working again
• Uninstalling k3s (k3s-uninstall.sh) solved the problem (internet started working)

Running Kubernetes with a competitive method (kind create cluster) makes no such problems.

I've used k3s on the very same machine months ago - everything was ok.

OS: Kubuntu 22.04
Internet connection method: cable

Another thing I don't like (which wasn't present in previous versions): tons of network connections are created in Network Manager, it seems that every time I deploy something using k8s, at least one new connection is created, which can be related to this problem, and is very annoying (I don't need those 'new connection' KDE confirmations every time I call kubectl apply).
