My audacity crashes when I add files and try to play them

Hi, every time I add my intro + outro on my podcast, it crashes! I’ve reinstalled Audacity a few times, and it happens with different files, so it’s not a problem with specific audio. When I add other files and try to edit by playing, it crashes. I can’t even copy the error message because it freezes the computer and I always have to “force quit” Audacity. I’m frustrated because I can’t edit my podcast anymore. I have the screen shot to send, but don’t see how in this message.

Which version of Audacity? (look in “Audacity menu > About Audacity”).
Which version of macOS?
