Velero Uninstall: Velero namespace stuck in "Terminating" state

[gh-noobie]

Hello everyone,

After uninstalling Velero, all resources were deleted, but the Velero namespace is stuck in a "Terminating" state. Has anyone encountered this before? If so, could you please share any solutions or workarounds that worked for you? I tried manually deleting the namespace with some commands, but it didn't work.
Velero version: v1.14.1
I tried these commands, but they didn't work:
velero uninstall
kubectl delete namespace velero --grace-period=0 --force
kubectl get ns velero -o json | jq '.spec.finalizers = []' | kubectl replace --raw "api/v1/namespaces/velero/finalize" -f -

Thank you in advance for your help!

kubectl get ns velero -oyaml

then we'll be able to see what's blocking.

@kaovilai, thank you for your response. I executed kubectl get ns velero -oyaml, and here is the result:

I also tried to install Velero by following the procedure outlined in this documentation:

This is not a velero specific issue. I recommend finding ways to get metric server back up.
