I believe the initialization failed because of UserID is incorrect after downgrade but I have no idea on what I can do to fix it.
Please let me know if any one have idea on what to do to fix it. Even if I'm wrong about the UserID, any solution to the problem would greatly be appreciated. Thank you.

Hi,
Firstly, if there are any third-party software installed, please disable them.
Secondly, I suggest you un-install printer drivers, then re-install them to see whether it works.
You may also check whether Print Spooler service has been started and start up type is set to Automatic.
In addition, please ensure that dependency services which are required for print spooler service are started.
