------------------------+--------------------------
 Running on macOS 13.4.1 (Ventura) on Intel CPU. Updated virt-manager from
 @4.1.0_0+quartz to @4.1.0_1+quartz and now it fails on start with this
 error (including the macOS crash reporter popping up):
 {{{
 objc[18842]: +[NSPlaceholderMutableString initialize] may have been in
 progress in another thread when fork() was called.
 objc[18842]: +[NSPlaceholderMutableString initialize] may have been in
 progress in another thread when fork() was called. We cannot safely call
 it or ignore it in the fork() child process. Crashing instead. Set a
 breakpoint on objc_initializeAfterForkError to debug.
 }}}

 Going back to virt-manager @4.1.0_0+quartz did not help and gave the same
 error. So I also tried to revert a few of the possible related ports from
 below list, but this also did not help.

 All the ports which have been updated as well:

 Any idea what else to try for resolving this?
