Launch crash - KeyboardHandler NullPointerException

  • Immediately after launching the snapshot, the game’s window briefly flashes in black and the game crashes.

  • Logs seem to indicate a failed check within LWJGL when calling method `com.mojang.blaze3d.platform.InputConstants.setupKeyboardCallbacks` during the game’s initialization.

Environment

Linux (Fedora 43), Prism Launcher, Mojang Java 25.0.1, LWJGL 3.4.1, NVIDIA 580.142 (RTX 2060 6GB)

Sorry about that! It doesn’t happen when using the vanilla launcher, I’ll be forwarding the bug report downstream to the Prism Launcher devs, thank you!
