SBIX crashes Glyphs 3

When creating a SBIX font, I cannot open that glyphs file anymore.
Steps to reproduce:

  • Create a new Latin font without any pre-populated glyphs
  • Add an iColor 128 layer to the space glyph (or any other created glyph)
  • drag any PNG on the layer
  • save the font and restart Glyphs 3 to open that file again
    → Glyphs crashes

(Glyphs 3.0.3 on MacBook Air M1)

Neue Schrift6.glyphs (866 Bytes)

Does it still happen in build 3100?

it works in 3100
