Hi I'm running Linux Mint 20.3 and was using the Viewer 1.0.11.q beta 11 perfectly well. Since upgrading to the newer Version 1.0.12.q Beta 12 it will not run at all. I have tried uninstalling and re-installing to no avail. Is there a link for the previous version please so i can get it working again?
Edit: Please see the message i got when i ran r-viewer from terminal
