Unable to remove provisioning cluster


I’m trying to provision RKE cluster through a Rancher 2.6.0 installed in a single node cluster (using k3s)
Everything seems fine until I have one node gets some issue with etcd.
But my problem is not there. The cluster is still in provisioning mode. While trying to delete it, it just stays there in the UI and does not terminates…
On the previous UI (2.5.x), deleting cluster even in provisioning state was not a problem.
Here, I just can’t find an issue…
Does anyone here has some advices?

Thanks in Advance,
