So it turns out my files or the AUP.3/Audacity project was corrupted. I could not open it because Audacity kept “Not Responding” basically. But I did some digging and was able to open my corrupted file and make it work like new.
There is another forum post regarding opening or recovering corrupted files. Here:
I just followed the instructions when opening the CMD black screen and typed what was needed, per the instructions. Keep in mind to recover any corrupted Audacity projects, you need to first install and Unzip the “Audacity Project Tools” from GitHub. I am not computer savvy, but If I can do it, anyone can do it.
Also, after the corrupted file was recovered, I was able to open it in audacity, then export the file as a WAV. file. Then I opened the exported WAV file in a new Audacity project. And wahlaa! It works MUCH BETTER, now with no freezes or crashes.
