I Use Microsoft.AspNetCore.Identity.EntityFrameworkCore in my project

When I try to update the user role I get the following error

InvalidOperationException: The instance of entity type ‘RoleEntity’
cannot be tracked because another instance with the same key value for
{‘Id’} is already being tracked. When attaching existing entities,
ensure that only one entity instance with a given key value is
attached. Consider using
‘DbContextOptionsBuilder.EnableSensitiveDataLogging’ to see the
conflicting key values.

My Code :

public async Task<Result> UpdateRoleAsync(UpdateRoleCommand command, CancellationToken cancellation)
 {
 var model = await _role.Roles.AsNoTracking().SingleOrDefaultAsync(s => s.Id == command.Id, cancellation);
 if(model== null)
 {
     //To Do
     return Result.Fail(FailMessage.Internal);
 }
 var config = new TypeAdapterConfig();
 config.NewConfig<RoleEntity, UpdateRoleCommand>()
     .Map(a => a.Name, b => b.Name)
     .Map(a => a.PresianName, b => b.PresianName)
     .Compile();
 model=command.Adapt<RoleEntity>(config);
 
 var result=await _role.UpdateAsync(model);
 if (result.Succeeded)
 {
     return Result.Success();
 }
 string error = string.Empty;
 foreach(var item in result.Errors)
 {
     error += item.Description + "n";
 }
 return Result.Fail(error);  
}
