Why does using `await` EF core execute command twice

public class UserAccountService(AppDBContext context) : ControllerBase, IUserAccountService
{
    private readonly AppDBContext _context = context;
    [HttpGet]
    public async Task<IEnumerable<UserAccountModel>> GetAccounts()
    {
        return await _context.Accounts.ToListAsync();
    }
}

public class UserAccountService(AppDBContext context) : ControllerBase, IUserAccountService
{
    private readonly AppDBContext _context = context;
    [HttpGet]
    public async Task<IEnumerable<UserAccountModel>> GetAccounts()
    {
        return await _context.Accounts.ToListAsync();
    }
}

builder.Services.AddScoped<IUserAccountService, UserAccountService>();

builder.Services.AddScoped<IUserAccountService, UserAccountService>();

protected override async Task OnInitializedAsync()
{
    var response = await UserAccountService.GetAccounts();
    if (response != null)
    {
        accounts = response.ToList();
        Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(accounts, Newtonsoft.Json.Formatting.Indented));
    }
    else
    {
       
    }

}
