After effect 2022 (beta) super slow on Mac 2021 M1

Hi everyone,

I'm going crazy about this and I hope someone could help me.

As in the title,  I'm using a Macbook pro 16 gb M1 and my after effects is letteraly unusable. Now I'm on a project that uses Animation Composer preset and I can't see the preview at all. I tryed to open the same project on another Macbook pro (2019) and everything goes easy. I comparated the render, memory, cache storage, preview settings, on both computers and everything seems to me ok and the same, but I can't see if there's someting I'm missimg or what. 

I only notinced that in my new computer when I press the spacebar for preview the cache blue/green bar becames uncolored, and restart the green from the start point. Then green go slow slow slow and stop. 

I'm not super expert on setting, so something maybe make no sense, but perhaps it could be helpful to understand what's wrong.

I have also read that many people are having issues with the native Mac M1, so at least I would like to understand if it is a problem with the computer.

Hope someone can help me, work is impossible in this conditions and I'll have to sell my computers otherwise.

Thank you
