Can confirm in 1.21.11

One way to fix the particle problem is by switching from multipart to variants and by specifying the particle textures in each model.

replace

 {
	"multipart":[
		{"when":{"down":false,"east":false,"north":false,"south":false,"up":false,"west":false},"apply":{"model":"block/red"}},
		{"when":{"down":false,"east":false,"north":false,"south":false,"up":false,"west":true},"apply":{"model":"block/blue"}}
	]
}

with

{
  "variants": {
    "west=true": { "model": "block/blue" },
    "west=false": { "model": "block/red" }
  }
}

Blocks:

{
 "parent": "block/cube_all",
 "textures": {
 "all": "block/red",
 "particle": "block/red"
 }
}

{
 "parent": "block/cube_all",
 "textures": {
 "all": "block/blue",
 "particle": "block/blue"
 }
}

Did you buy Bedrock on PC? If you bought Minecraft Bedrock on Xbox or mobile, that purchase only works on that platform and doesn’t include Java Edition for PC. The “Java & Bedrock Edition” bundle only applies to Windows PC purchases. Make sure you’re logged into the same Microsoft account you used to buy the game. If you bought it on Xbox, you can only play it there unless you purchase the Windows PC version separately.

I have the same problem on my Mac OS Lion.
