Cura crashes on startup

[brigant52 0]

Hello, my cura randomly crahed  yesterday and now it crashes right after Startup. I've already unistalled and deleted all files, after reinstalling it still crashes.

The crash log ends when loading OpenGL shaders. You've got newer graphics drivers than me installed (but the same card!), so let me update them and see if it breaks for me too.

Nope, that isn't it. Try opening Cura a few times again and post the log so we can see if it always crashes at the same point.

Yeah, it always crashes at the same point.cura.log

It crashes every time after this:

So I may have been wrong on the graphics idea, since it makes it reliably past that. Although a crash to desktop without even a warning makes it harder to try and diagnose 😕 

 

At this point I'll suggest the program version of "reboot it". Uninstall it, make sure it didn't leave any files behind (default installation location is C:\Program Files\UltiMaker Cura 5.5.0 ), redownload the installer (in case it got corrupted or something) and install it again.

If that doesn't work, try installing another version (either 5.4 or the 5.6 beta) and see if that makes a difference.
