Can’t help you with APK’s but I can with KODI. I don’t use Firesticks and I’d recommend the $20 ONN 4K Box at Walmart. But let’s see if it’s something with KODI that you can fix now on your stick. Do you use a Build or Addons? If so what Addons are you using? What version of KODI do you have? Most addons are optimized to work with KODI 20 and above. Is your Real Debrid sub up to date with days left?
I don’t think it’s the hardware. I think its something to do with the sources of the addons/apks you are using. Have you used the methods described on Troypoint to set up your firestick? They don’t always work as written but at least we’ll know what you have and are doing.
I don’t believe that the root cause of the issue is your device. Though for apps suddenly crashing (please elaborate), if it’s not a software conflict, it could be a thermal issue with device cooling.
The device wouldn’t cause a sudden lack of RD sources not to appear. You should double check and make sure your RD sub is still current on their site.
Worst case, a factory reset and fresh install isn’t a bad idea. I used to do a factory reset and reinstall once a year when I was using firesticks.
I don’t do that nearly as often, nor does the need warrant it, since switching over to my Shield Pro a couple years back.
