ID 575175 - A large number of audio clips in a SBP project can cause an import to fail

Problem summary
A large number of audio clips in a SBP project can cause an import to fail
 
Customer reported version
flix_6.6.2
 
Customer reported platform
mac.13
 
Steps to reproduce
 
1)Create a SBP project and add more than 60 audio clips (each should be a part from a large audio file) on multiple audio tracks

2)Import the SBP project to Flix
 
Expected behaviour
Import should finish without any errors
 
Actual behaviour
SBP exports all the required media and Flix can transfer all files to the Flix server. The import process fails during the audio mixdown process without any errors in the logs, just with a red banner in the Flix client.
 
Workaround
1. Export the audio from SBP separately as an MP3, remove all audio from the SBP project and import that version to Flix. Import the MP3 generated in the beginning of this workaround separately to Flix
2. Change the audio clips in SBP to be each its own audio file instead of being a part of a large audio file
3. Combine the audio clips into a few audio files
