Thank you for your feedback, what items are you holding in hand?

It looks like getAmplifier is a big value

It's a creative apple from the 1.17.1 fabric apple & carrot mod.

The creative apple amplifier is 9(level 10).

When amplifier is greater than 5(level 6), the effect is same to level 6, that each tick (non-game tick) to restore 1 health (0.5 heart).

I don't know if this was involved in the crash but I was also using a mod that compacts the health bar if there's over 10 hearts.
It's Health Overlay (Fabric).

I'm pretty sure #149 has fixed it, and now just need to wait for merging
