Problem Details:

Osu was working fine until today, it crashes when I launch it. I tried doing a full reinstall in a different folder and that one crashes too. Osu repair.exe crashes as well. I updated my GPU drivers and restarted the PC, didn't work. I haven't updated my windows 10 lately so that can't be the problem. Idk what to do anymore, please help.

osu! version: 20180416.4 (latest)

Do you get an error or a picture of a crying pippi? Click her and post the log contents here. Or just copy any errors or whatnot. If you don't get anything, or just a basic Windows error, check Event Viewer.

I'm not getting a crying girl, just the basic "osu stopped working" window. This is the description in the event viewer:
Failed to schedule Software Protection service for re-start at 2018-05-20T20:40:38Z. Error Code: 0x80070002.

Not sure what this error means...

Edit: I used System file checker to see if there was any broken system files and it says there's nothing wrong.

The log that you looked at has nothing to do with osu!. Hit Ctrl+F and search for "osu!" so that only osu! related logs show up. There is a nice guide with pictures here.

Is this it?

Filter your logs by "Error" and after that is done try searching for logs containing osu! one more time.

Sorry I'm bad at this but I think it's this one

Make sure you are using 32 bit color depth and not anything else.

If you are already using 32 bit color, try reinstalling your graphics drivers, something may have gone wrong there.

Solved.

I used "amd cleanup utility" to uninstall all my gpu drivers and apps, then installed the latest driver available for my gpu and Osu works fine now.
