System Error

I have version 10.0 Yosemite on my Mac. For some reason, whenever I try to use Audacity, it states:

The system has detected that another copy of Audacity is running.
Running two copies of Audacity simultaneously may cause
data loss or cause your system to crash.

Use the New or Open commands in the currently running Audacity
process to open multiple projects simultaneously.

When I try to find the other copy, it doesn’t work. What could the issue be?

There’s a lock file that gets stuck and it tells the systems not to step on a running Audacity (whether there’s an Audacity there or not).

And any minute now I’m going to find out where it is.

It is in Audacity’s temp folder. See https://forum.audacityteam.org/t/audacity-is-already-running-error-solved/40481/2
