Missing au files?

So, I was working on one of my projects today (I was using 2.3.2) and suddenly out of nowhere, the app crashes and freezes my screen. I don’t know what exactly happened to cause this, but I had no choice but to restart my computer. I try recovering the project and suddenly it says that most of the au files are missing and it gives me a choice to (temporarily or permanently) replace them with complete silence.

I hadn’t moved, renamed, or done anything with the files beforehand, and I have no idea what caused this, but some of the files just seem to be gone. Others are still in the project folder, but it seems like the program can’t access them. Is there any way to fix this or to recover the missing files? Any help would be greatly appreciated.

Unfortunately there is probably no way to fix or recover the missing files.

I would recommend updating to Audacity 2.4.2 at your earliest convenience (Audacity ® | Download for Windows). This will not help to recover that project, but it may help to avoid similar problems in the future.
