plotting – Getting error while introducing star symbol

I am interested in creating a star symbol in Mathematica. But I am getting some error saying Nonatomic expression expected at position 1 in First. How to over come this error. I am using Mathematica 12.2 version in ubuntu 18.

star = First[
  First[ImportString[
    ExportString[Style["✶", FontSize -> 16], "PDF"], 
    "PDF", "TextMode" -> "Outlines"]]]
emptyhex = 
 Graphics[{EdgeForm[{Thickness[.1], Black}], White, star}, 
  ImageSize -> 30]
filledhex = Graphics[{EdgeForm[], Black, star}, ImageSize -> 30]
