Please help! Audacity failed to read/write...Any way to recover??

Hello,
I just recorded a forty minute interview in Audacity 3.1.3 on Windows 11. I had edited about half of it and then got an error message saying Failed to write when I went to resave and failed to read when I try to open it, no matter how many times I try. My problem is, the recording I did of myself I recorded in Audacity and never exported it to an audio file. All I have is the project file, which I now cannot open. Is there any way to fix this at all or is it lost forever?? Thanks in advance!

Matt
