[🐛 Bug]: Ruby - Selenium Manager throwing error

[kevin-roe]

What happened?

When running tests today Selenium started failing with this message:

/Users/kevin.roe/.asdf/installs/ruby/3.1.2/lib/ruby/gems/3.1.0/gems/selenium-webdriver-4.25.0/lib/selenium/webdriver/common/selenium_manager.rb:79:in `run': undefined method `positive?' for nil:NilClass (NoMethodError)

          return result unless status.exitstatus.positive? || result.nil?

I was able to reproduce the issue with this simple code:

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :chrome
driver.get("https://www.google.com")
driver.quit

I tracked it down to here, where the command is returning pid 4961 SIGKILL (signal 9) on the status on line 67, causing line 79 to eventually cause the process to die.

This randomly started happening to me earlier today, and eventually 4 other members of my team started experiencing this as well. I don't have a ton of knowledge on how Selenium Manager works, but due to the random nature of this I imagine some process on my machine is pulling in some updated version of the bin/macos/seneium-manager executable and that is causing problems, but that's just my best guess.

How can we reproduce the issue?

gem install selenium-webdriver -v 4.25.0


```ruby
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :chrome
driver.get("https://www.google.com")
driver.quit

We were able to fix the problem by reverting back to 4.24.0. We also had to uninstall 4.25.0 for the fix to work
