Audition crashes when trying to relink audio file in multi-track

I have an edited podcast with several interviews and all files are in a multitrack, but for some odd reason each file is linking to one audio file. The correct files are still named in the multitrack timeline.

So I tried to delete the one file that is playing for all my tracks, when I do that all clips in the timeline say offline.

I then tried to relink media with the correct file but I get the spinning beachball of death and audition will crash.

Thankfully I exported the entire podcast and can edit it, but I wanted to edit my working file.

Any ideas? And yes, my backup file is doing the same thing. I can go back a few versions, but then lose changes.  Why does Audition do this? I haven't moved my files.
