Just had this happen too and it is very troubling, just updated recently to 2019.12 and now having tons of import audio issues.
This one was a session in our edit room which i had just opened multiple times in the edit room, then imported the session data into our mix room and on import gave the message about " invalid bounds etc.." same message as this user is reporting and it replaced a bunch of audio within the session. Did not save, went back into the edit room and now the edit room session is giving the same message and we now have lost a lot of work that is due to be mixed tomorrow!!
