Issue Description

Getting a Failed to load command error when running multi_scan. This doesn't happen consistently, so it makes understanding why it's happening that much more confusing.

Complete output when running fastlane, including the stack trace and command used

bundler: failed to load command: fastlane (/Users/distiller/project/vendor/bundle/ruby/2.6.0/bin/fastlane)

Environment

Same as here: https://github.com/lyndsey-ferguson/fastlane-plugin-test_center/issues/209

FastlaneCore::Interface::FastlaneTestFailure: [!] Tests have failed
  /Users/distiller/project/vendor/bundle/ruby/2.6.0/gems/fastlane-2.137.0/fastlane_core/lib/fastlane_core/ui/interface.rb:172:in `test_failure!'

Is telling you that tests failed. If you set :fail_build to false, it won't throw when your tests failed.

[lyndsey-ferguson]

As to why you're getting this:

bundler: failed to load command: fastlane (/Users/distiller/project/vendor/bundle/ruby/2.6.0/bin/fastlane)

I'm not sure yet.

[lyndsey-ferguson]

This has a similar pattern:
https://github.com/fastlane/fastlane/issues/11071

[jordan-romeroporter-earnin]

So for the first part, we need the fail_build so that way it returns the correct exit code & prevents the flow of execution on our CI

[jordan-romeroporter-earnin]

For your follow up - the changes we made were double checked and didn't seem to have any syntax issues - however we did include --verbose into every single run of multi_scan...so I wonder if that's inducing it?

[lyndsey-ferguson]

Try without it and let me know if that changes anything

[jordan-romeroporter-earnin]

We're confident that's the problem.

[jordan-romeroporter-earnin]

However, is there a way to keep --verbose without it failing?
