There is no (simple) fix.  Your ancient version of Kodi isn't developed any more and I doubt you will find a developer willing to try to spend days/weeks of their time trying to backport the current addons just to support your old version, considering how cheaply you can get a more modern device

Only the current version of Kodi is supported/developed, you of course are free to run any version you like, however old versions will eventually start to break down as the developers and community leave them behind

Only solution is to look at a new device and I would start here
