If your Kodi is crashing all the time, then the best fix is to do a fresh start and reconfigure your Kodi. There are many reasons why your Kodi maybe crashing regularly. These include:

  1. Faulty plugin/addon
  2. Corrupted file
  3. Device memory shortage
  4. Congested setup
  5. ISP speed
  6. Faulty memory cards
  7. Hardware decoding problems
  8. Video decoding issues
  9. Virus on device

To correctly diagnose where your problem is, I recommend, backing up your setup and install a fresh build and test to see if problem still exist. Sometimes, you may also have to clean up device as well.

You can easily install a complete fresh setup using the Configurator for Kodi app
