We have enabled sessions as we need them in our site, I am using Stackify Prefix and I've noticed on the first load after a local IIS reset (version 10) 2 errors are being thrown.

System.Data.SqlClient.SqlException: There is already an object named 'Sessions' in the database.

This is using the standard Episerver session config on the https://world.episerver.com/digital-experience-cloud-service/development-considerations/session-state/.

Does anyone know why this is, I know there's an underlying but in entity framework when using initalization config migrations, is this related to that?

I do not think this is realted to EPiServer but probably to EntityFramework as you are suspecting as well. But please update thread here anyway if you find the cause so others can learn from your findings.
