Watir browser initialization failing due to Selenium argument error

I am suddenly getting an error when initializing a Watir browser. Using current versions of watir-rails and selenium-webdriver gems.

When initializing a chrome headless browser:

browser = Watir::Browser.new :chrome, args: %w[--headless --no-sandbox --disable-dev-shm-usage --disable-gpu --remote-debugging-port=9222]

I get the following error that seems to be caused by a discrepancy with Selenium's expected arguments:

# /usr/local/bundle/gems/selenium-webdriver-4.6.1/lib/selenium/webdriver/common/driver.rb:319:in `create_bridge'

2023-01-03 18:11:30 WARN Watir [DEPRECATION] ["args_keyword", "capabilities"] :args to initialize Browser is deprecated. Use :args inside Hash with :options key instead; see explanation for this deprecation: http://watir.com/guides/capabilities.html.

As per the warning at the bottom and this SO post, watir selenium: unrecognized arguments for Browser constructor, I have attempted changing the initialization:

BROWSER_OPTIONS = %w[--headless --no-sandbox --disable-dev-shm-usage --disable-gpu --remote-debugging-port=9222]

browser = Watir::Browser.new :chrome, options: {args: BROWSER_OPTIONS}

However I am getting the same error (without the deprecation warning)

The issue is that you need Watir 7 to work with Selenium 4. Please upgrade to the latest version of Watir and it will work.
