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
isacc crash minidump
When I disconnect my monitor, everything works fine.
Edit: forgot to mention that the failing function in isaac dump was WglMakeCurrent(). So, when i called GetLastError() in my application (with hope there is the same problem) it returned ERROR_INVALID_HANDLE(6)

HI @Lombeelo, welcome the GFLW forum,
That is very odd, I’ve not seen this behaviour before simply due to connecting a monitor.
WglMakeCurrent
is a win32 function, so this failing is really low level and there’s not much GLFW can do, unless somehow GLFW has set up the context incorrectly, though I would have expected an earlier error for that.
- Could you try updating drivers in case this might be the issue?
- Do you have any other OpenGL programs which do not use GLFW which work when the monitor is attached?
- I am supposing you have 2 monitors (laptop+external) attached with both displaying. Which is the primary monitor in this case and does changing that change the issue?
- How exactly do you launch + observe the issue the application?
- Could you run DXDiag and check the Display tab Notes for any reported issues?
Thank you for your reply. I tinkered with my computer a bit more and found out that deleting drivers for all displays + GPU in device manager then restarting helped me. I will write all other things you asked me just in case it will help make GLFW better.
- When I tried deleting opengl32.dll I found out that steam was using it and was working totally fine
- Yes I use exact setup, laptop display is primary
- Isaac was launched from steam and immediatly crashed without any messages and minidump file was generated by the game itself. It’s attached in first post. Also I was launching my own application from Visual Studio 2022 wich compiled with precompiled GLFW library in ImGui repository link (github.com). Error message is in the first post
- Checked it before fix - there were no issues.

So you have resolved the issue completely?
When I tried deleting opengl32.dll
I would not recommend deleting opengl32.dll
, this is a system dll which comes with Windows. The actual OpenGL driver is installed with your GPU drivers.
