bin/rails aborted! with stacktrace involving prism and bundled_gems.rb

When using the snap on Ubuntu 24.04.3, then installing rails, then creating a new rails project causes crash/error stacktrace (see below).

Steps to reproduce the problem

1. Install ruby with sudo snap install ruby --classic
2. gem install rails, which by default goes into ~/.gem
3. Running rails new store will display bin/rails aborted! and a stacktrace that I'll paste below
4. The project does get created, but running any of the following will crash with a similar stacktrace:

• bin/rails server
• bin/rails db:create

Expected behavior

No stacktrace.

Actual behavior

The commands do no succeed and produce the following:

Tái hiện lỗi trên Ubuntu 24.04.3 bằng các lệnh snap, gem install và Rails được nêu, sau đó so sánh các đường dẫn stacktrace trong prism.rb và bundled_gems.rb với đường dẫn tải rubocop-ast. Công việc hoàn tất khi rails new, bin/rails server và bin/rails db:create chạy mà không có các cảnh báo Prism hoặc NameError.
