I got the same error after switching the game to fullscreen from 680x820; sorry I don't have much else to add. You could possibly find a way to change your resolution from the osu folder and see if that helps. There should be threads on how to do that here or a quick search on google should also bring you to it.

If you get a "Unable to find Intel ICD OpenGL" error at the same time you get this error, read this;

Please make sure your Intel graphics drivers are up to date. Intel released a fix for this specific issue in all of their driver versions 15.46 and higher. If you get your graphics drivers through a computer manufacturer, they may use a different versioning scheme and their most recent drivers may still have this issue. It is good idea to download them directly from Intel's website.

Temporary solutions include: Running osu! with integrated graphics and disabling compatibility mode if applicable. It is highly recommended you fix this issue permanently by downloading up to date drivers.

If you believe you have enabled compatibility mode, navigate to your osu! folder and edit the file "osu!.pcname.cfg". Verify that the line "CompatibilityContext" is set to 0. If it is not, change it and save the file. Otherwise, this was not the cause.

Another temporary solution would maybe be changing fullscreen to 0 in the cfg file, but I highly suggest trying to fix it for good.
