Grafana pod container is in CRASHLOOPBACKOFF state

Hello Everyone,
I have deployed my kube-Prometheus-stack helm chart on k8s, everything was working fine but today suddenly my Prometheus-stack-grafana pods gone in

CrashLoopBackOff state

, when I checked it was not able to create grafana container and got below warning in grafana-container logs, anyone face this issue previously ?
Any suggestion/solution will be great help.
