I'm getting this error when trying to run the tool on linux:
./PixelAnnotationTool_x86_64_v1.3.2.AppImage: symbol lookup error: /usr/lib/libharfbuzz.so.0: undefined symbol: FT_Done_MM_Var
I tried running it on the latest updates of:

• Arch linux
• Fedora 32

with harfbuzz installed on both and I'm getting the same error.
