No idea how would this happen
The mod Borderless Mining was a temporary modification from comp500 himself, in detail, read comp500/BorderlessMining#26

Probably happens just because it uses GLFW before my prelaunch entrypoint runs; I'm not sure if there's a way around this, maybe an entrypoint prior to opening the BLS window could be made?
See comp500/BorderlessMining@0d42a0d for the relevant code that the Borderless Mining test builds use.
