Answer 1

This looks more like an error thrown by your OS's memory manager instead of the compiler, most probably you are trying to access a NULL pointer somewhere.

Just run the program in a debugger to track this down in your program.

First Thankyou for answering, but The code work fine, for Eg if I copy the same code Into Shader.cpp and Shader.h It work but when I try to pack Into .dll This error show up, I am using Visual Studio 2019, Trying to learn OpenGL and The code become a mess too quickly, like camera, shader, texture and I thought why not try to write library for each of them It will be organized .......... ........... aaaannd this issue left me unorganized :( .
