When opening a job item for review, a process tries to determine if sources has been changed or not.
This process is currently poorly optimized, leading to very long loading times for job items with many tags, to the point where it can exceed max execution time and cause a timeout.
It can happen for some nodes with a lot of paragraphs with a lot of fields, for example.
Rework \Drupal\tmgmt\Form\JobItemForm::trackChangedSource() to reduce the amount of calls to \Drupal\tmgmt\Data::flatten().

MR with proposed changes open and the related patch for composer.
In my case (huge job item), the call to the trackChangedSource method has been reduced from 83.88773 seconds to 0.34245.
The calls to the flatten method from the trackChangedSource method has been reduced from 1966 occurrences to 1.
I hope tests will pass even if I believe so, given the changes I made.
