In recent updates (starting around After Effects 2022/2023), Adobe renamed several legacy effects. If you are searching for "Lens Blur" in the Effects & Presets panel and finding nothing, it is likely because the effect is now listed under a different name or falls under the "Camera Lens Blur" umbrella.
Right-click After Effects > "Run as Administrator." This grants permission for plugins to register in the effects menu.
