I am sorry to hear about this. What I think is happening is that the deCONZ response is invalid which causes Hue Essentials to crash on app start. Would it be possible for you to share your bridge config?
You can do this by sending a HTTP GET request to the following URL:
deconzip is the IP address of your deCONZ gateway and
username is key you generated using the API. Please send the response to email@example.com and I will look into it. If it is indeed an incorrect value it should be easy to fix.
If you need more detailed instructions please let me know.
