Everything was fine, today I installed it because I wanted to see if this program would be my new day-to-day drawing program. I opened the program and minutes later I was looking at the options hoping I would make everything comfortable for me.

The thing is, I was messing around with the windows locations presets, I clicked on one and then suddenly the program crashed and I went on a problem that I want to reverse but don't know how to since the program keeps crashing upon starting.

It has to do with OpenGL and this is what it says on the window upon a crash.
"QSurfaceFormat(version 3.0, options QFlags <QSurfaceFormat::FormatOption>(DeprecatedFunctions),depthBufferSize 24, redBufferSize-1, greenBufferSize -1, blueBufferSize -1, alphaBuffersize -1, stencilBuffersize 8, samples -1, swapBehavior QSurfaceFormat::SwapBehavior(DoubleBuffer), swapInterval 0, profile QSurfaceFormat::OpgenGLContextProfile(CompatibilityProfile)).

Help? I tried uninstalling and installing again but it didn't help :C

Try to reset the settings. Uninstalling doesn't do that. See https://docs.krita.org/en/KritaFAQ.html ... figuration

It looks like you enabled opengl directly instead of angle, while the GPU in your system comes with broken opengl drivers.
