Can’t seem to download kodi 17 successfully

Hi
I have an Amazon Fire stick with Kodi 16.1 installed at the moment but have been trying various ways of updating to Kodi 17 without much success.
I can install ver 17 but when I go to launch the Kodi app it shows the Kodi v17 start up screen then goes blank and kicks me out of the Kodi app.

I have ensured that the two settings in the developer options are on before trying to download v17.1 .

I have tried downloader and Es

Any help would be much appreciated
