Kontakt GUI Closing Problem in Nuendo 11

Hi Steinberg, sorry if my English is bad…
There’s an issue whenever I close Kontakt’s GUI after loading an instrument, it cause Nuendo to stop working (yes, Stopped working, no action was available) for about 1-2 minutes every time, and on every track.
I’m using Win10, Intel 11700k processor, 64g ram, Samsung evo 970 pro 2t+ 14t 7200 harddrive

Hi,

Not exactly the sale problem, but since last Kontakt update each time I open the instrument it freezes for about 10 secs. Ans sometimes Nuendo ends up crashing.

I’m in Big Sur on a 2019 MacBookPro.

Thanks for your advices.

B.
