Thanks for your PR.

Unfortunately, this won't fix the issue you're seeing. For that, we'll need to compile against EF Core 8.0 for the compiler to target the new LoadAsync() signature taking a LoadOptions parameter, which is a much bigger fix that requires targeting .NET 8.0 and referencing the EF Core 8.0 packages.

I opened #1789 to track that and informed the EF team this breaking change is not documented: dotnet/efcore#30306 (comment).

My fault.

Will you accept pr if I change this line
await reference.LoadAsync(cancellationToken)
to this
await reference.Query().ToListAsync(cancellationToken);
as a workaround?

It will send the exact same query to a database.

@kevinchalet any comments regarding new approach?

It's likely a good workaround (thanks!), but I'd like to hear back from the EF folks before changing anything.
