Kodi just won’t open anymore

Hi, sorry if I’ve posted in the wrong spot, but I wasn’t fully sure where to post the issue I’m having…..I had Jarvis working on my laptop but decided to update to the latest version…so put Krypton on, now I can’t even get Kodi to open, the windows blue circle appears, and then just disappears and nothing happens. I’ve tried going back to Jarvis, and then tried Krypton again…..no luck…..have tried using the exe file that worked on my desktop pc…..any ideas please? I’m not super tech savvy but if given instructions I know how to follow them!

TIA
