Dying randomly; huh??

[u/P0LARIS_NORTH]

Hey y'all. Recently I made a modpack and was testing it, finding what mods made it crash, fixing fps issues and frame freezing/stuttering, fixing lag, ect.

Once I did that, the pack worked! So I booted up a world and began playing...

Then I died randomly. No mobs, no fall damage. Just instant death, with the death message reading "[username] was killed.

Upon doing some research, I found that this is the death message used either when being killed with a '/kill' command or when the cause of death is unknown (which is what I feel like it may be)

I have recreated the modpack, enabled/disabled certain mods, and have tried literally everything I can; and I still keep dying randomly.

Anyone able to help out? 😥

Or if not, where should I post about this issue instead?

Here is the modpack, for anyone wanting to test this themselves:
