6.5 crashes when using audio warp or changing algo

I am trying to time warp stuff in a project and when changing the algo to “standard solo” the file is re-analyzed but since 6.5 it gets trapped in a loop - till Nuendo crashes… Nasty nasty…

I just made a video. Please watch, everything else is hard to explain. This is happening 100% of the time. I have now to find a way to change the algo because I dislike the sound of “elastique pro” when it comes to time warp instruments and vocals.

I have to say: That file / event is only 20 sec long but was processed offline with Antares Autotune before.

Ok - update… I rendered that Event to a new file, deleted the trash - the new file is set automatically to standard solo because I set that in the prefs - so I want to warp a FRESH FILE - same re-analyzing loop till crash.

Ok… update… it is working in 6.07…

WHAT THE F+CK…

I am dealing since 2 h with that issue - time is running out over here.
