I’m working off a Mac Catalina. I worked on a rather large file with about 5 track and 1 hour of edited material. I saved it multiple times throughout the process as an audacity file. Then I saved the whole file to restart the mac. After the restart, I opened the file, it still shows all tracks and edits I did on the tracks but none of the waveforms appear and no audio plays.
I even waited for about 30 minutes. In case they need loading time. Still no audio. How can I reconnect the files? Please help.
The files have not been moved or renamed.
