Ruby crashes during `require "tk"` on Mac OS 15

I am on Mac OS 15.2 M2, using Ruby 3.4.1 which is installed from chruby, and it seems that #33 has reappeared:

Beginne damit, require "tk" in irb auf Mac OS 15.2 mit Ruby 3.4.1 zu reproduzieren, und vergleiche anschließend das Verhalten mit issue #33. Verfolge den Initialisierungspfad durch die Stackframes von tcltklib.bundle und libtk8.6.dylib; abgeschlossen ist die Aufgabe, wenn das Require von tk Ruby auf dem gemeldeten Setup nicht mehr beendet.
