What does "failed to map shmem for window ffffffff" mean ?

os : Ventura OS

xcode : xcode 14.0 beta

my app : macOS

When I build my app in xcode 14.0beta, I got the log "failed to map shmem for window ffffffff" many times. Fortunately it seems like no problem in my app. When I searched this log in google, unfortunately there is no clue.

I'm wondering why I got this log. please give me any information about this log. thank you !
