I am not able to fix this error since while and not getting any clue how to fix this "webhook is not ready" error

I have installed istio in my AWS eks cluster.
istiod and istio-ingressgateway both are running.
My application is not able to up because istio sidecar injection has been failed.
I check logs in istiod it shows following error.

2023-12-20T09:34:03.507373Z error controllers error handling istio-validator-istio-system, retrying (retry count: 1059): webhook is not ready, retry controller=validation

Can anyone guide me on this what is wrong ?
