All of them? Where are they located?
BTW, if you click on the white center of your error screen, then do Ctrl-A (select), Clrl-C (copy), you can then Ctrl-V (paste) the details of the error message into your forum report.
If this happens with all of your .aup3 files and you have tried rebooting, reinstalling Audacity, and resetting your configuration, it is possible that you are having a “sqlite3.rc”: “14”,“sqlite3.context”: “DBConnection::ModeConfig” error, reported by previously by a user. See also: Failed to open database file
In that prior I recommended these three (3) steps:
-
Run Tools > Reset Configuration
-
Uninstall all versions of Audacity, and then Install Audacity 3.0.4[now 3.0.5] from Audacity ® | Downloads
-
It may be worthwhile perusing these forum posts that also reported a sqlite3 error 14:
Project saved will not reopen or allow export of audio file
Unable to open AUP File Between PCs - #11 by SirenAria
Error; Cannot open a new empty project [SOLVED]
Audacity is unusable
We never did hear back from that user, so please keep us filled in…
Perhaps someone else and/or the prior user will chime in.
