Created attachment 55001 [details] unhandled exception at osu launch.
Osu! worked fine with few bugs for me until today (2 July 2016). I'm on Ubuntu 16.04. The game does not start anymore. The wine window starts and informs me that osu!.exe crashed. I get a message about an unhandled exception that I join.
This bug appeared as I was playing in osu!. Osu! crashed and never started again. In the same time , I doing the automatic update of Ubuntu which of course contained an upgrade of winehq.
Could you try making a new clean prefix for Osu! and try running it again? Perhaps this was something related to the update you are referring to?
OK I am so sorry it totally worked. The problem was that my installation was old and was done with osu!.exe instead of osu!install.exe. I truly apologize for boring you :)
