"Google::Cloud::Vision.image_annotator" crashes Puma app server in Rails controller, but same code runs fine as a standalone ruby script

A few clarifying questions:

1. By "crash" do you mean some kind of operating system process crash, like a segmentation fault or something? (Sorry, I'm unfamiliar with what those look like in Windows.)
2. Is the difference between the succeeding standalone script and the crashing Rails app only the fact that Rails is running in the latter? i.e. are you running on the same Windows workstation in both cases? How are you launching Rails? Do you have some kind of Windows-based Rails launcher, or are you starting it with rails server? Do you have any fancy auto-reloading or process caching system like bootsnap running in your Rails setup, and if so can you try turning those off?
3. I assume you have googleauth 1.11.0 in your bundle. As an experiment, can you try downgrading the googleauth gem to version 1.8.1 and retry?

1. Sorry I could have been clearer. The Puma server shuts down immediately, without warning or logging anything. So just the app server that is responsible for executing the rails controller code halts, there is not an OS crash. The web server and other processes do not go down with it.
2. Yes both running on the same Windows workstation. My development setup uses PowerShell 7.4.2, so I'll have usually a handful of PowerShell windows open, running processes. The core stack is nginx as https, Puma 6.4.2 (ruby 3.3.3-p89) as the Rails 7.1.3 server, and Sidekiq 7.2.2 that runs a few worker tasks on startup or for mail processing (none of which are proc'ing when I do these tests). All of the processes are started manually via various bat scripts, but ultimately they boil down to the simple commands of rails server, bundle exec sidekiq etc. so there is nothing fancy or automated in my development environment.
   When I execute the successful standalone script, it's also done through a PowerShell window
3. There are two Google gems installed from my Gemfile currently: gem 'googleauth', '~> 1.11' and gem 'google-cloud-vision' (and of course all their dependencies). I will try the downgrade at next opportunity and report back!

As a bit of further info re: all other pieces of the auth chain working, I have been working around this by not using the gem features and instead doing direct https calls to the Google Cloud Vision API successfully and seeing it tracked on Cloud Console. So all the auth info seems to be correct, fwiw.
