AME stuck on Connecting to project in AE

Hi,
I noticed a lot of similar issues on this topic, but no clear solution... I have one project with 4 compositions, and in between rendering them, I got this problem. If I export, nothing happens - if I add to queue, AME starts connecting to project but never succeeds.

AE 22.0.0

AME 22.0

Mac Big Sur 11.5.2

allready cleared my caches.

Thanks for helping!
