Dear experts,

We encountered below NSXPC issue that is similar with one in https://www.mail-archive.com/pythonmac-sig@python.org/msg12027.html, below issue happened in python3.9 with MacOS Monterey and Sonoma.

I also see below workaround in https://www.mail-archive.com/pythonmac-sig@python.org/msg12027.html, do you have any suggestion on resolving above our issue? That is not 100% reproducible, only happen randomly. Thanks. 

      This is a change in behaviour in macOS. The workaround is to create an 
      NSApplication instance, for example by calling 
      Cocoa.NSApplication.sharedApplication().

Thanks,
Zhi
