Please check the devworkspace first

$ oc get devworkspace

If found, delete the DevWorkspace resource instead of the deployment directly

$ oc delete devworkspace <workspace-name>

Please check the potential parent resources

$ oc get all -l component=workspace036c85e5c44e4207

Also, please share the below files further discussion

$ oc get deployment workspace036c85e5c44e4207 -o yaml | grep -A 5 ownerReferences
$ oc get events --sort-by='.lastTimestamp' | grep workspace036c85e5c44e4207
