ProcessJobQueueTask InjectorNotFoundException

[AndyBurson]

We are using queued jobs in association with gridfieldqueuedexport in order to export a large CSV report.

After performing a recent SS upgrade, the system has stopped working. Specifically, an error is generated when the ProcessJobQueueTask runs for the first time (i.e. when first running the queued job).

The error generated is:

[2019-07-01 14:31:57] Running Export a CSV of a Gridfield and others from queue 2. ERROR [Emergency]: Uncaught SilverStripe\Core\Injector\InjectorNotFoundException: ReflectionException: Class SilverStripe\Forms\GridField\FormAction\StateStore.Report does not exist in /var/www/enable-consumer-test/httpdocs/vendor/silverstripe/framework/src/Core/Injector/InjectionCreator.php:17

FYI, the current non-working versions are:

silverstripe/cms (4.3.3 )
symbiote/silverstripe-queuedjobs (4.3.2)
silverstripe/gridfieldqueuedexport (2.2.0)

If I downgrade to earlier versions, the export works correctly:

silverstripe/cms (4.2.3 )
symbiote/silverstripe-queuedjobs (4.3.1)
silverstripe/gridfieldqueuedexport (2.1.1)

Interesting. Are you able to get a stack trace?

I've attached the full stack trace (it's quite long).

The site is running on Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-116-generic x86_64).
