Question Paper Server Error

[LeSpirit]

Hi!
I've changed some values of spigot.yml & bukkit.yml files earlier and the server was running just fine.
But I've been optimizing my paper server (1.19.2) by changing some values of yml files and the server won't run and keep crashes...
Can anyone help me...?

Your config is invalid, specifically the "optimize-explosions" setting
