The cause is not clear, but it crashes shortly after starting, and in one log very-shortly after add-ons are loaded; so I'll guess the cause is an incompatible add-on (perhaps not updated for K22 alpha).
Skins (and the many add-ons they depend upon sometimes) are a common cause for major crashes, so perhaps delete the skin add-on to force Kodi to default back to Estuary and see if that helps.
If not, you need to hunt down the problem add-on. Stop Kodi, rename /storage/.kodi to /storage/.kodi-old and copy essential config over, e.g. sources and add-on settings. Then restart kodi and start reinstalling add-ons from repos. Either it all works (problem solved) or at some point you install something and problems start; then you know which add-on is the cause.
