V4.1 Insert entity when the entity has unique constraint

I set the table Forums_Group's Name column with unique constraint.
And when i insert data,i get the error "System.InvalidOperationException:“The property 'Id' on entity type 'ForumGroup' has a temporary value while attempting to change the entity's state to 'Unchanged'. Either set a permanent value explicitly or ensure that the database is configured to generate values for this property.” at
method GetFullErrorTextAndRollbackEntityChanges in EfRepository class .
I search it online,and some people said it is bug of Entity Framework Core,might be this info can help you to resolve this.
Thanks.

I am doing a fresh installation of nopCommerce 4.1 on a production server with Microsoft SQL Server Express 2017.

The installation is failing with the following error:

Setup failed: The property 'Id' on entity type 'Store' has a temporary value while attempting to change the entity's state to 'Unchanged'. Either set a permanent value explicitly or ensure that the database is configured to generate values for this property.

Please advise how to fix this issue.

Anyone have idea on this?
