I also get the same problem.
level=error msg="provider.kubernetes: got error while updating resource" deployment=slow-queue error="Operation cannot be fulfilled on deployments.apps "slow-queue": the object has been modified; please apply your changes to the latest version and try again" kind=deployment namespace=project-queue-job update="latest->latest"

Can anyone help me figure out how I can find the cause of this problem?

keel version is keel:0.18.1
