Autopilot when enabled, in practice fails to work at bare minimum on the new A35K, resulting in the aircraft either performing a 3000 fpm dive, or 6000 fpm nose up manuever, resulting in crashes seconds after departure from busy airports like EGLL.

Same issue on my end, LNAV overcorrects the heading and setting a VS results in either a rapid climb or descent, i also had the aircraft level itself out to 0fpm and then within 30 seconds gradually increase to 4000+
There was an in-game OTA rollout before the App Store release. That means you can get the 35K update just by restarting the game. However, this 35K build has an AP bug. The bug will be fixed once you update to version 26.3 via the App Store. This is how I resolved the issue.
I just had this issue departing Sydney a bit ago, and it also manifested with the aircraft randomly turning away from the heading i had set with autopilot
I think the faulty OTA for build 35K is to blame. It’s incompatible with version 26.2, which caused the “bug”. The issue will be gone once we properly update to 26.3.
