Kubernetes Dashboard无信息显示且报未知错误，求助排查

访问Kubernetes Dashboard时界面无法显示任何内容，报错提示“Resource Not Found”：

已检查版本信息：

$ kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.26.0
Kustomize Version: v4.5.7
Server Version: v1.26.0+k3s1

客户端与服务端版本一致，但问题未解决。随后将kubectl和k3s服务端版本降级后，错误仍然存在：

Client Version: v1.25.0
Kustomize Version: v4.5.7
Server Version: v1.25.6+k3s1

$ kubectl get clusterrolebinding admin-user
NAME         ROLE                        AGE
admin-user   ClusterRole/cluster-admin   19h

$ kubectl get sa -n kubernetes-dashboard
NAME                   SECRETS   AGE
default                0         19h
kubernetes-dashboard   0         19h
admin-user             0         19h

恳请帮忙排查该问题。
