Hello @pushpadubey031,
According to data governance documentation, when we export a segment to a destination then data governance policy is applied automatically, I think this error occurred because any one policy have stopped to export data.

First i would like to suggest you check your segments, Which attributes or events have been used their, which labels are applied on these attributes.

You can also get more details in your policy violation message which policy creating a problem etc.
Thanks.
