After update to .NET 7, I get an error : System.ArgumentException: An item with the same key has already been added - entity-framework-core

Question

I created a project with ASP.NET Core 6 and developed it over time.
Now I updated this project to .NET 7.
So far there have been no problems. I had no errors at runtime. The program works correctly.
After the update, when I run the add--migration command, I encounter an error whose origin is unknown.
I updated all nuget packages of the program.
Add-Migration -name test2 Build started... Build succeeded.
