Hi, I have cura 3.1.0 running flawlessly on my LinuxMint 19.3. I would like to use 4.4 so I downloaded cura 4.4.1 and tried to start it from the app image but it shows a fatal error right at launch. Can anyone help? My System specs are: Linux Mint 19.3 Kernel 5.0.0-32-generic(x86_64) AMD Athlon X2 2.6ghz 8gb ram nvidia gt710 1gb The error message is: Traceback (most recent call last): File
