Crash on my computer

[Lombeelo]

TLDR: glfw somehow broke on my computer (not anyone other's) and i don't know how to fix it without reinstalling Windows.

As I was developing my application using glfw, it stopped starting with those messages:

GLFW Error 65544: WGL: Failed to make context current
GLFW Error 65543: WGL: A forward compatible OpenGL context requested but WGL_ARB_create_context is unavailable
GLFW Error 65544: WGL: Failed to clear current context

I was using precompiled library packed with ImGui. GLFW crashed in glfwCreateWindow().

So... I checked the source code of GLFW for any hints and got nothing. Then i tried to open The Binding of Isaac: Repentance, wich also uses GLFW, and it silently crashes and leaves a crash dump with analysis result below.

I checked wglMakeCurrent in Windows, It returns ERROR_INVALID_HANDLE.

[Lombeelo]

Found the culprit! Error happens when i have my second monitor connected :) Fuck you, Microsoft.
Btw when calling GetDC() inside EnumerateWindows() it gets dc for every window on every screen.

As I understand it from your question on the forum this issue was resolved after you cleaned the GPU and display drivers and reinstalled them.
