[26.2] Weird crash when jumping in water

[Maker261]

I was trying to see the new c2me addon in action, and see how well it does with my gpu.
but all of the sudden, the moment I jumped into water (2 block tall or more), the mojang logo appeared on my screen and then the game kicked me out of my singleplayer world.

I then looked at the logs and spotted the error which points towards your mod.

I even tried with just the mod alone (dependency mod included), and the same thing happens.
