Working on a project for a few days and exporting to audio without issue.
I just put Finality on a snare track and it sounded great.
Then I went to export audio and Sonar crashed.
I removed Finality and export is fine.
 
Error window:
 
A fatal error has occurred.
 
Module: c:\program files\cakewalk\vstplugins\Joey Sturgis TonesFinality Advanced\Finality Advanced.dll
 
 

Freeze the snare track that will lock in the sound and disable the offending effect.
That is unless that effect crashes during freeze.
 
You can also try disabling fast bounce too.

I tried to freeze track and that crashed.
 
I had installed vst-2 version so I decided to uninstall that one and try vst-3 version and now it's working.
I will continue to test this weekend.
 
Thanks bitman

Hey, alright!
Glad you got it sorted.
