I deleted lock file per instructions. Didn't fix (subsequent attempts to launch Audacity replaced the lock file, though, FYI).
No new audio devices, plug-ins or other audio software of any sort added in past several years. I have no anti-virus app.
The first few times I tried to launch Audacity, "LoginWindow" became the active application (and remained so until I switched to another app). Subsequent attempts to launch, this did not happen. However, Activity Monitor shows that "LoginWindow" is still active.
FYI, here's what Console is reading:
