URGENT: Problem with MySql setup

Dear All

I have Keycloak in Ubuntu 20.04 and MySql 8.0.23.

during the setup, its works perfectly fine but when i restart Keycloak service, after that i am getting below error.
2021-03-15 20:26:04,618 FATAL [org.keycloak.services] (ServerService Thread Pool – 68) Error during startup: java.lang.RuntimeException: Exception invoking method [listUnrunChangeSets] on object [liquibase.Liquibase@3445ce69], using arguments [null,(),false]

Caused by: java.lang.ClassCastException: class java.time.LocalDateTime cannot be cast to class java.lang.String (java.time.LocalDateTime and java.lang.String are in module java.base of loader ‘bootstrap’)

Please suggest what wrong i am doing
i drop the DB and recreate again, its working, but again after service restart same error.
