System.TypeLoadException with generic attribute on C# model (dotnet-typegen 5.0.1)

I use generic attribute on models for FluentValidation.Auto package with automatic model validation

Model:

[ExportTsInterface]
[Validator<UserWalletValidator>]
public sealed record JUserWalletEditable(int ID, string Name, string Address);

sealed class UserWalletValidator : AbstractValidator<JUserWalletEditable>
{
    static readonly Regex addressValidator = new("^T[A-Za-z1-9]{33,35}$");

    public UserWalletValidator()
    {
        RuleFor(f => f.Name).NotEmpty().MinimumLength(4).MaximumLength(64);
        RuleFor(f => f.Address).NotEmpty()
                               .MaximumLength(36)
                               .Custom((s, ctx) =>
                                       {
                                           if (!addressValidator.IsMatch(s))
                                               ctx.AddFailure("Invalid TRC20 address");
                                       });
    }
}

Run dotnet-typegen generate -c tgconfig.json and exception occured:
