Current Behavior
obs-studio crashes in deps/glad/src/glad.c:
7053│ static void find_coreGL(void) {
7054│ const char *v = (const char *)glGetString(GL_VERSION);
7055├───────> int major = v[0] - '0';
7056│ int minor = v[2] - '0';
The documentation says that this function can return 0.
obs-studio should report the error properly instead of crashing.
Steps to Reproduce
n/a
Anything else we should know?
There is no error, glGetString returned nullptr probably because there are no extensions available.

Research direction
Start in deps/glad/src/glad.c at find_coreGL and inspect how glGetString(GL_VERSION) is used when it returns nullptr. Confirm the null-return path on FreeBSD and ensure OBS reports the graphics initialization error instead of dereferencing the result; the issue does not name a test to run.
