It looks like your local omemo key store is damaged, but I’m not sure. Have you tried to delete stored key material?

Thanks for the reply paul.

Its look like that problem has been resolved now by deleting stored key material. But i’m not getting this that how omemo key store has damaged. Could you please help me with this.
