Can’t launch it

I have a Bbox Miami running Android TV Lollipop. I have been running Kodi Jarvis and Krypton 17 & 17.1 smoothly so far. Then i decided to give Kodi 18 a try.
No problem to sideload and install.
BUT ! Nothing happened when i launch it. No, not exactly nothing : It get launched, and right after first cache setup it close itself. And no way to launch it again. And upgrading a previous installation is the same.
I know it’s still at nightly stage, but just wondering if anyone else get same behavior ?
Does anyone have a suggestion?
