Recent update has led to multiple crashes. Please fix

Cannot read properties of undefined (reading 'beforeQueued')

This error keeps cropping up whenever I try to run Instant queue option. Please fix. Thanks

Reproduce the crash while using the Instant queue option and trace the reported undefined beforeQueued access to its source. Confirm the queue completes without the crash and add or run a regression test covering this path; the issue does not name any files or existing tests.
