I know it is kinda late but I thought if someone else has the same issue it might be useful to have another possible solution.

I had the same issues: first i had to enable i2c manually and then i got this AsyncWorker error.  
In my case the issue was that explorerhat was always on version0.4.2 even with updating/upgrading. I fixed it by removing it entirely: `sudo apt-get --purge remove python3-explorerhat`  
and then following the steps indicated by sandyjmacdonald: [Explorer HAT install instructions - #4 by sandyjmacdonald](https://forums.pimoroni.com/t/explorer-hat-install-instructions/515/4)

`git clone http://github.com/pimoroni/explorer-hat`  
then  
`cd explorer-hat/library`  
then  
`sudo python setup.py install`

now it is on version 0.5.1 and works just fine.
