I was copy/pasting it into the main track
I'm pretty sure that's not the best way to assemble a show, although it seems like it should work.
I would open each song and segment in its own track and then use the Time Shift Tool (Sideways Black Arrows) to push each track sooner and later so the end of one and the beginning of another line up.

And then leave them there. Audacity will push all the tracks into one show (squashed top to bottom) when you export. This track juggling act also lets you fade between two songs by simply overlapping them and use the volume tools to fade one out while you're fading the other in.
That also lets you talk over music by dipping the music volume while you're speaking at normal volume. Those are all overlapping tracks which would be a nightmare if you tried to do it all one one pasted track.
Do you have WAV sound files as backup for all your work? It's a common New User error to cut and edit with the one and only copy of the sound. If anything happens to the edit or the computer, you have to record or download it all again.
What I think may have happened is you ran out of resources. Most times when you make a change or edit, Audacity makes a very high quality copy of
the whole show as UNDO. If you've been editing for weeks, then there are that many copies of the show taking up space. It goes away if you save a Project and close Audacity, but if you never closed the program, there's tons of data back there. Sooner or later, you're going to run out of space.
