Kontakt not syncing with Ableton Live 11 in Windows 11

Windows 11 (update is from around February of this year)

i913700K (8 performance cores overclocked and stable to around 5.43 and the 16 goofy efficiency cores are disabled in BIOS, because they were causing issues in Live, which has been well documented all over the net for the last year+) I built this machine thinking I wouldn't have any performance issues… and it took me months and months to learn that the efficiency architecture is for the birds, and parking cores is definitely a huge nono in Windows 11, because… Microsoft go brrr when they code anything apparently… I miss my XP buikld, but I digress)

128 GB DDR5 (stock speed)

Live 11.3.13

Kontakt 7.10.5 (EXT sync set to on/off, tried different buffer settings [currently locked and maxed all the way to the right letting my memory do all the heavy lifting] and other settings in Kontakt, no change - and this option that this thread is mentioning, to force the buffer rates, doesn't exist in the current version of Kontakt anymore… which is really nice, so I can't try that.)

Damage 1 and The Score are having sync issues with Live. With Damage 1, if I make a midi clip using a note representing the 'loop key', then it will come out of time as soon as it completes the loop and circles around. If I 'drag the midi' from the patch, onto a track in Live, then that works perfectly.
The Score - with any combination of notes in a midi clip, will not stay in sync once the clip loops and circles around… it "drifts" out of time, same thing with the example for Damage 1 above. The track latency for The Score is -50 ms to make it be in perfect time, but again… once the clip loops, it starts drifting. This is with EXT on and off in Kontakt and all kinds of other attempts to see what's causing this.

I tried multiple other libraries in Kontakt, of which I have myriad… and from around 10+, mostly percussive based, I had zero issues and they all looped beautifully and stayed in sync for minutes worth of testing. The Empire Breaks library that is referenced in this thread was one of the ones I tested… after reading this thread, I made sure to test that one, lol… stays in sync and loops like a charm.

Does anyone have a clue why Kontakt is having these sync issues? And where is N.I. to discuss this????

(gonna make a seperate thread in the hopes that this gains some traction, apologies if that annoys anyone)

Thanks in advance to anyone who has the time to help me with this - I really want to get down with The Score, and I was eagerly awaiting some future sales/deals at Sonuscore, because I wanted to pick up the rest of their synths with the Ensemble engine, but not if it's going to archaic and not understand simple midi sync.
