Can't get Creality Print Ver V7.0.0.4127 to run in LMDE 6

Hello.

I’ve been attempting to run the latest version of Creality Print on my computer which is running LMDE 6 as the OS, but have not been abler to even get the software to open up. I click on the icon and nothing happens. I downloaded the “CrealityPrint-V7.0.0.4127-x86_64-Release.AppImage” file and made the file excutable using both the graphical interface and the command line. What have I missed?

Thanks in advance for your help here,

Shawn C.
