I have recently purchased the VST/VST3 plugin Spiff from oeksound for transient fun.

Audition 2020 scanned the effects (I have rescan existing disabled) with no problem, and the effect operates as expected.

Audition 2021 seems to "stop" when it comes to spiff_64 and "never" finishes - I've only let it try for about 15 minutes, but it just sat there, never making progress. I did this twice - the second time it did the scan in a different order, saving spiff for last. However, when it got to spiff at the 97% mark, it just stopped again.

Note, ALL of Audition 2021 did not freeze! I could actually cancel out of the dialog and continue to use the application. However spiff was not added to the plugin list, so I can't use it in the 2021 version.

I am on Windows 10 x64 (kept up to date) and this problem is appearing in Audition 14.0.0.36.
