Its a bit hard to open the linux version since I am having trouble going over the codes, is there a specific tutorial on how to open PNGTuber Plus for Linux?

I had to make the file executable by typing

chmod +x "PNGTuberPlus LINUX v1.2.1.x86_64"

into the command line. After that it should run no problem launching from command line or just double clicking in the file explorer.

Depending on your distro you might be able to do this through the properties window as well by checking the "Allow this file to run as a program" box.
