Latency in Logic Pro 11 / Kontakt 7 on macOS 14 Sonoma

Post updating to Sonoma in Mac I am getting serious latency with Kontakt 7 in Logic Pro 11. The buffer size in Logic is set to 64. Also in the past I could record the audio first and then play it and record midi post. But now unable to do it. MG2 only works playing live. What am I missing. Please help MG2 or MG3 are unusable at this time. Very frustrating. Thanks

No issues here on my Mac. What is the spec of your machine and audio interface?

MacBook Pro M1 16 GB ram. UAD twin X Quad. Logic Pro at 64 buffer size runs smoothly with multiple tracks of BBC SO Pro, SWAMs, Kontakt, Logic session players at 20% CPU. Also the Low latency Mode is engaged. Also noticed that SWAM instruments play at pretty low latency (not noticeable). GEOshred is almost instant.

Thanks for your support.
