StandardRB 1.44.0 breaks Ruby LSP integration with unrecognized cop errors

[jacobduba]

Description

After upgrading from Standard Ruby 1.43.0 to 1.44.0, the Ruby LSP integration breaks with numerous "unrecognized cop" errors. The issue persists even after downgrading back to 1.43.0 unless the gem is completely removed and reinstalled.

Environment

• Ruby version: 3.3.6
• Standard Ruby version: 1.44.0
• Ruby LSP version: 0.23.6
• RuboCop version: 1.70.0

Steps to Reproduce

1. Start with a working setup using Standard Ruby 1.43.0
2. Upgrade to Standard Ruby 1.44.0
3. Attempt to use Ruby LSP

Current Behavior

The Ruby LSP fails to initialize with hundreds of "unrecognized cop" errors, starting with:

Error loading addons:
/var/home/jduba/Bench/vipreply.ai/vendor/bundle/ruby/3.3.0/gems/rubocop-1.70.0/lib/rubocop/cop/registry.rb:68:in `dismiss': Cop RuboCop::Cop::Cop could not be dismissed (RuntimeError)

Followed by numerous errors like:

unrecognized cop or department Bundler/DuplicatedGem found in /var/home/jduba/.rbenv/versions/3.3.6/lib/ruby/gems/3.3.0/gems/standard-1.44.0/config/base.yml

Workaround

I found this workaround:

1. Remove Standard Ruby completely
2. Reinstall version 1.43.0

Simply downgrading the version without removal doesn't resolve the issue.

How strange we ran into that problem while upgrading, and fixed the issue, which is around the namespace iirc. I'll look into it, thanks.
