Installed Ubuntu 22.10 and KODI with no problems. In Ubuntu 22.04 and earlier versions KODI is a Hidden folder in the Home directory.That doesn't seem to be the case for U-22.10. I was able to find a kodi4 folder under the user folder but the layout is not quite the same as the previous versions folders. Normally I do not use flatpack or snap to install programs.(personal preference) May have used flatpac in his case. Found KODI folder exactly where Tes said it would be. Thanks.
I found mine. I will bet you used flatpak install?
The folder should be in home/USERNAME/.var/app/tv.kodi.kodi
