When I have the same reoccuring problem with Panthalassa mod installed on 1.19.2 with the newest release of the mod and Forge. When the game launches it does not bring it to the red Minecraft bar loading screen it stays white. And then windows reports the window no longer responds and there is no choice but to end the task. Ive let it sit for 15+ minutes and it does not load. However if I remove the mod it loads up perfectly fine.
