Stack level too deep at xmldecl encoding method

Beginne damit, den Rails-Konsolenfehler mit Ruby 2.6.6, asdf-vm und REXML 3.2.5 zu reproduzieren, und untersuche anschließend die in den Warnungen genannten REXML-Dateien, einschließlich rexml/xmltokens.rb, namespace.rb, entity.rb, doctype.rb und text.rb. Die Aufgabe ist abgeschlossen, wenn die Warnungen zu doppelten Konstanten und der Fehler stack-level-too-deep in diesem Setup nicht mehr auftreten.

Hi there!
I just update my Mac OS X to Monterey and made a fresh install of my project in the development environment.
I'm using rexml as a dependency for rubocop and I've installed ruby 2.6.6 using asdf-vm.

When I try to start a rails console, I get the following error:
