Potential fix

Downgrade dependencies to

k8s.io/api v0.26.4
k8s.io/apimachinery v0.26.4
k8s.io/client-go v0.26.4

This happened with us as well after the recent update to client-go >= 0.27

The type ResourceEventHandlerRegistration is added to client-go from v0.26.0. But the v0.27.0 updates the code. So the problem occurs after update the client-go to " >= v0.27.0".

I don't think that's actually true or do you mean >= v0.27.0?
Because downgrading the deps from 0.27 to 0.26 actually fixed the issue for me.

The type ResourceEventHandlerRegistration is added to client-go from v0.26.0. But it is different with 0.27.0.
0.26.0:
type ResourceEventHandlerRegistration interface{}
0.26.4
type ResourceEventHandlerRegistration interface{}
0.27.0

type ResourceEventHandlerRegistration interface {
	// HasSynced reports if both the parent has synced and all pre-sync
	// events have been delivered.
	HasSynced() [bool](https://pkg.go.dev/builtin#bool)
}

Here is the fix: https://github.com/kubernetes/client-go/issues/1245#issuecomment-1523434471 . But the latest controller-runtime release (0.14.6) doesn't contain the fix PR.
