How to run multiple Audacity instances?

I use Audacity to record and cut audio. However it (as of version 3.2.4) does not allow editing a project while an other project is recording. The simple solution I found is to start an other audacity instance, but with different XDG_DATA_HOME environment. Run eg. XDG_DATA_HOME=~/.local/share/2 audacity to get a (somewhat) separate instance. It may prompt you to "restore" a not properly closed project, but it's probably the one which is opened by the other instance currently. Just ignore it.
