I was using Blender 2.8 Beta fine, and then when I went to Edit > Preferences, is crashed. Now on startup, it spits this error and then immediately closes.
"al lib (EE) getchannelmap failed to match front-center channel (2) in channel map"
Getting this written down was a pain because of that. I tried deleting the preferences folder... and installing a different build of Blender 2.8, but it still won't start.
