Adding node crashes cluster

[bensode]

Proxmox 6.0-7 5 nodes. When I added the 6th node the entire cluster goes down, gui becomes unresponsive on all nodes and unable to log into the newly added node at all from UI. Shelled into each of the nodes and run pvecm status with this result. I've restarted corosync on each nodes and waited a few moments but it doesn't sync up and I lose connectivity to most if not all VMs already on the cluster until I shut down the newly added node.

I'd like to add that it displays in the GUI but not in the node list. How can I remove the node properly now to rebuild it?
