I'm also running this application on a cloud VM. It works well now.
So I all changed libraries versions to the same with cloud's But still same error.
I think it's only happening on macOS.
Could it be a problem of latest MacOS?

Could you provide code snippet that we can reproduce this locally?

My code is not that special, just simply using ccxt async support code.
But after upgrading my macOS version to 14.5 (sonoma),
there is a crash with ccxt async support and fastapi-utils library which I use for scheduling job on async code with @repeat_every decorator.
