I just installed the latest version of FAF (2023_12_1). In general new versions of FAF have worked fine for me over the years however I now get the following error message when I run FAF on my PC.
FAF 2023_12_1 Crashes on Launch.
Try re-downloading the installer and re-installing. It looks like the download may have been corrupted. I just installed 2023.12.1 today on Linux and it worked fine.
