The issue is in both net8.0 and net9.0

the test:

using Xunit;

namespace Tests;

public interface IInterface<TEntity, in TContext>
    where TEntity : IInterface<TEntity, TContext>
{
    public static void Method<TEntityProperty>()
        where TEntityProperty : IInterface<TEntityProperty, TContext> { }
}

public class UnitTests
{
    [Fact]
    public void TheTest() { }
}

Compiler gives no errors.
The test gives error :

By removing the "in" in type parameter TContext eliminates that error

For non-static method, the compiler does report error about constraint:

public interface IInterface<TEntity, in TContext>
    where TEntity : IInterface<TEntity, TContext>
{
    public void Method<TEntityProperty>() // CS1961
        where TEntityProperty : IInterface<TEntityProperty, TContext>
    { }
}

However, there's no error for a static method with manual this;

    public static void Method<TEntityProperty>(IInterface<TEntity, TContext> @this)
        where TEntityProperty : IInterface<TEntityProperty, TContext>
    { 
    }
