This probably is caused by the latest version of glib, version 2.74.0,2. There is no issue when using glib-2.72.2,2 pcre-8.45_1 and pcre2-10.40

The issue is reported at luakit GitHub https://github.com/luakit/luakit/issues?q=%231005 issues #1005 and #1010

A possible fix is given at the GitHub site and FreeBSD Forum at https://forums.freebsd.org/threads/luakit-browser-wont-start-any-solution.86683/#post-583554

TIA, meine
