@tilo With the current Ruby 3.2.0dev https://github.com/ruby/ruby/commit/56cc3e99b6b9ec004255280337f6b8353f5e5b06, it looks like no error according to the latest build.

Can you try the latest Ruby 3.2 head to reproduce?

I was running into the same error and tried to reproduce it. In the end I just saw the error with rake 11, but was unable to repro with the current rake. I assume you'll be able to fix the problem by bumping rake to the most current version which appears to support ruby 3.2 just fine.
