I confirmed none of these mods are causing the crash; however, the affected mod (Friends & Foes) prevents me from using any of its addons due to the world tick crashing error.

Should be fixed, with the latest release of the mod mentioned in the last comment :)

Based on the crash log, there is nothing wrong with Friends&Foes, seems like something straight in the NeoForge.

What kind of server/launcher is this?

Based on the latest log i can see its caused by https://www.curseforge.com/minecraft/mc-mods/aggroindicator
