Please see https://forum.audacityteam.org/t/fix-for-audacity-2-1-1-not-launching/39157/1 for the probable solution. The solution requires editing or deleting the audacity.cfg settings file, as described in the topic.
If you could attach the audacity.cfg file that was causing the problem, that would assist us. Please rename the file to “audacity.txt” in order to attach it. Please see here for how to attach files: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1
