ME 2019 won't import files from PP 2019

I'm trying to do something I've done hundreds, if not thousands, of times before, that is, export a section of a timeline from !Premiere Pro to !Media Encoder in order to make an MP2 file that I can upload to my media server on my TV station. But since I installed the latest Adobe update, the export from Premiere is not going into Media Encoder properly.  I know that Dynamic Link Manager is running, I can see it in my Task Manager.  So, I set an in and an out point on my timeline in Premiere, then press CTRL+M to open the Export Settings window.  I make sure I have the correct format and preset, click on the Output Name to enter the name and folder location for the export, then I click on the Queue button at the bottom.  What normally happens is that the Media Encoder window opens and the segment appears in the Queue window.  But now, after I click on the Queue button in the Export Settings window, nothing happens:  Media Encoder does not open automatically, and when I go to Media Encoder, there is nothing in the Queue window.

I figured out a workaround, but it is a PITA involving marking my timeline in Premiere, saving the project, then using ME's File->Add Premiere Pro Sequence menu option and checking all the settings to make sure that it's right in ME.  But, I really like the ease and simplicity I get with the Dynamic Link between ME and PP.

I live in Las Vegas, and I know there are a lot of people from Adobe here for the NAB convention, but I need to get this done right away.
