Inventory Profiles Version : 1.1.2
Running Forge Mod loader.
i don't know why it is happening but it's crashing. if i roll back to a previous version it doesn't crash anymore.
I have no idea what is causing it.

Downgrading the mod or upgrading java should fix it. Your world should be unaffected.

Which launcher do you use?
you java looks very old.

Same here. Before I even enter my world, it already crashed.
