Comment (by hexane360):

 I've found a solution. The following patch fixes the problem in
 src/vtetypebuiltins.cc.template:

 }}}

 All it needs is logic to patch only on Ventura and higher, and then it can
 be merged.

 The root cause is Apple changed the calling convention of __atomic_load.
 Gstreamer had the same problem with the Ventura update.
