I had the same issue, and these two steps solved my problem.

Increase addon_job_timeout
Check node free space (at lease 15%)

In my case, one of the nodes had DiskPressure state

that's resolved by below command and I created a network interface:

docker network create --driver=bridge --subnet=10.43.0.0/16 br0_rke
