Hi, @J Worth
Thank you for posting in Microsoft Q&A forum.
Based on the provided context, it seems that the OSD Task Sequence progress bar disappears once it reaches the Setup Windows and Configuration Manager step. This issue might be caused by the use of an unattended.xml file with the "Skip User OOBE" set to "true," which is no longer supported.
To get the OSD progress bar to show again, you can try to remove the custom SetupComplete.cmd file, if there is any.
To do this, add a Run Command Line task between the Apply Operating System and Setup Windows and ConfigMgr tasks, and enter the following command in the command line:
cmd.exe /c del SetupComplete.cmd %OSDTargetSystemDrive%\Windows\Setup\Scripts /F /Q
Alternatively, if it's specified in a Run Command Line task between the Apply Operating System and Setup Windows and ConfigMgr tasks, remove the Run Command Line task from the task sequence.
