Error importing. Not sure what's going on.

I am trying to open a project but get the error. Error Importing. I did the trick where you move the data folder underneath the project, but that does not work. I may need to share the files so someone can fix it.

What is the full and complete error message?

It asks me to open the project through the “File> Open command” option. It sadly does not work.

Is it just one specific project that has this problem?
If you create and save a new project, are you able to successfully reopen it?
Which exact version of Audacity are you using?

All other projects open perfectly. Only this one is having issues. 2.1.2 I do have the newest version installed also.

Please attach the .aup file to your reply.

The current version of Audacity is 2.4.2. I would strongly recommend that you use that version until Audacity 3.0.0 is released (due out soon).
You can get 2.4.2 via the Audacity website:
