Basj, seems there are several of us reporting frequent crashes with Start11, with no feedback or progress on a fix. I've provided you details from Event viewer in my latest update. Where does this stand? Looks like Start11 maybe shouldn't have been released yet -- too buggy, crashes constantly.
For my part, I'm running Windows 11. I bought Start11 and Object Desktop, because I need the the ability organize my Start Menu like we could with the built-in Windows 10 menu, and Windows 11 has taken that away. Start 11 would be a great solution for this... if it worked.
