this is weird and not great… when i SAVE AS a new audio file and select “current file” and format “wav default”… the resulting save is a text file… and if i close that audio file… the audio is gone forever… replaced by the useless text file.
what’s going on!? i’ve lost a bunch of work today…
some more experimenting here. definitely the first time i try to save a WAV it saves as a txt file.
so, before closing the file i saved as an AIFF… and that worked fine, then i saved as a WAV again and that time it worked OK…
but it seems the first save saves as a text file…
back to 10 i go!
How do you exactly proceed to save a file? Can you verify the settings in the file format dialog?
I have never been reported this case, and this is obviously a common function.
Is the data actually text or just the extension.
the data was actually text… and the file size tiny…
yes, for sure something you didn’t fail to check! 
but, i’m saving the same way i have for years…
audio file open… shift-S to save… “current file” selected (not “project”) format = Wav default
it also only seems to happen with a newly created file (in my case, a file recorded into WaveLab… it doesn’t happen if i open a WAV and re-save it… only a file that hasn’t been saved yet)
i’m on an iMac running Catalina.
Maybe I was misled when you said “save is a text file”. Indeed, there is a bug, which is simply that the .wav extension is not added to the filename. But the file created is not text, this is normal .wav contents. See workaround here:
ah, let me look into that! thanks… when i opened the file it opened in a text editor with strange text, which is why i assume it was a “text file”… and i will double check the file size again…
today on my next job i will go back to 11 and go through my usual steps to test again, and then add the .wav extension to see if it fixes.
