To fix the issue temporary, changed runAsNonRoot: false => runAsNonRoot: true
But, the fix warn me about using runAsNonRoot

Warning: would violate PodSecurity "restricted:latest": runAsNonRoot != true (pod must not set securityContext.runAsNonRoot=false)
 

The affected version we noticed 4.12.10

Upgrade from 4.11.20 to 4.12.10

1. install ocp on azure cluster version 4.11.20
2. Upgrade the cluster to version 4.12.10

Upgrade stuck due to failure in csi-snapshot-controller-operator

Upgrade done smooth

1. The cluster is running on Azure
2. Installed using IPI
3. Storage classes
