Error when installing 0.6.3

[ettmetal]

The Issue

When running $ sudo ./figma-linux-0.6.3.AppImage -i, the following error is produced, meaning that I am unable to integrate the AppImage:

./figma-linux-0.6.3.AppImage: 2: Syntax error: newline unexpected

OS Info

I'm running Pop!_OS 20.04 LTS, an Ubuntu derivative

I know there's not a lot of detail here, so please let me know if there's anything else I can provide :)

Did you try to install appimage sudo ./figma-linux-0.6.1.AppImage -i ?

Sorry, I mistranscribed the command (I'll update the main issue), but yes, that is the exact command which provokes the error. A different error is produced when trying to run the AppImage:

$ ./figma-linux-0.6.3.AppImage
./figma-linux-0.6.3.AppImage: line 1: syntax error near unexpected token `newline'
./figma-linux-0.6.3.AppImage: line 1: `<?xml version="1.0" encoding="UTF-8"?>'
