I have the same issue, my fix was to add async and await keyword since I am calling an async method on my business logic.

   var results = _repository.GetAllDataAsync(); 
   return Ok(results);
}

To this one:

HttpGet]
public async Task Get()
{
   var results = await _repository.GetAllDataAsync();
   return Ok(results);
}
