It is a known issue that pipeline jobs that are in progress prior to an upgrade may not resume successfully after an upgrade. The same is true for jobs that may have hit an error condition if they are retried after an upgrade. In general, hotfix releases should not have incompatibilities when resuming jobs, but major version transitions will sometimes exhibit this problem. When possible, it is recommended to let jobs complete prior to performing an upgrade.
To check the status of jobs, use the Pipeline link from the Admin Console
