I'm running k3s 1.26.4 on a small 4 nodes home lab cluster (1 master/worker + 3 workers).
Today, the master node crashed, and a forced reboot was the only solution.
Since then, the master node refuses to start correctly.
In the logs, I can see a lot of v1.Event to conversion errors. Here is an extract:

Has anyone already had a similar issue, and how you solved it ? I have to admit, I'm a bit lost on what is happening here...
