If you have an Audacity project that cannot be opened, or where Audacity throws an error or crashes upon opening it, please attach your project file to this issue so we can investigate it. It’s also sometimes possible to recover some data from corrupted projects.
Needless to say, preventing data corruption is a high priority for us, and anything we manage to identify and fix will be addressed in an upcoming patch release.
Did you send an email to the devs so they know you need help? It’s given in the link in the first post in this thread. This forum is mostly frequented by other users.
@teetow means please attach your project file to the GitHub issue that link points to, NOT to this forum discussion. Placing files in this topic will not get you help as quickly as submitting them where they’ll be seen by the development team. (Specifically, again, that GitHub issue the OP linked to:)
