Noise Reduction takes ages in Audition 23.1

Hey everyone,

I use Audition mainly for postprocessing the sounds for the videos I produce. So far anytime I used Noise reduction, it worked like a charm. My videos are usually like 1 hour long, so I process the entire source file prior to the actual video editing. One hour long file usually took like 30 seconds to process. Now, with the updated Audition 23.1 it takes AGES... 20-30 minutes and the estimate gradually increases. Never really reached the end even though I was VERY patient.

When I reverted the version back to 23.0, it started working smooth and quick again. The question is - is there some bug that causes this long processing or am I missing some super advanced next-gen setting, that causes this (and I can turn it off)?

Thank you, dear community.
