For this recipe
{
"type": "ars_nouveau:crush",
"input": {
"tag": "minecraft:quartz_block"
},
"output": [
{
"chance": 1.0,
"count": 3,
"item": "minecraft:nether_quartz"
},
{
"chance": 0.5,
"count": 1,
"item": "minecraft:nether_quartz"
}
]
}

Tag needs to be changed to item, because it generates a barrier block.

minecraft:nether_quartz also needs to be minecraft:quartz

Minecraft: 1.20.1
