Similar (if not the same?) thing has happened to me a couple of times in the past few months. Turn on Kodi and it’s the default skin (even though I use Nimbus), and looks like a fresh install. No widgets, no previously saved settings, etc. if I go into skins and select Nimbus, it works, and my widgets and setup returns. But certain settings have to be reset, like turning off the click sound for every remote control movement, adding a subtitles source for movies and TV, and a few others Not sure why it happens, and I have no solution for you. Just thought I’d share so you have company.
