1.20.5 Pre-Release 1 introduced changes to how the particle command works. The syntax for particles with extra options no longer works as it previously did and this is intentional. The following particle types may be affected:

• minecraft:block
• minecraft:dust
• minecraft:falling_dust
• minecraft:item
• minecraft:vibration
• minecraft:block_marker
• minecraft:dust_color_transition
• minecraft:sculk_charge
• minecraft:shriek
