Elements 2023 Organizer does not respond

Hi

I have recently installed Elements 2023. I am using Windows 10. I am using dual extended screens.

I opened Organizer to import edited images from my folders.
It first imported my General catalog from my previous version 2018

When I try to open "Import" to load new images from my folders , I do not get a dropdown menu to select an option. I wanted to check if my set-up was correct and tried to open File. This would also not provide a drop-down menu. I checked Edit, View & Help, none of them produced the appropriate menus.

In the organizer itself, none of the following Tabs produce the appropriate dropdown menu :Sort by, Create or Share, but tabs, Media, People, Places events and Search all worked perfectly.

I am also able to open an image in Organizer and access the Grid from the open image.

I rebooted and tried again, same non responsive Tabs. I rebooted, opened the editor and accessed the Organizer from there. Still no response from the Tabs.

To check to see if I had a mouse or computer problem, I opened my existing Elements 2018. It worked perfectly. However when I closed 2018 a message appeared saying "my free trial would expire in 18 days".
I have a fully paid up version 2018? 
I rebooted and opened 2023 Organizer again, still no response from the Tabs. I clicked Import a few times, both left and right clicks. Still no reponse.

I opened an image in Organizer, when suddenly the Import Window opened in my second monitor. No drop down options menu was displayed, it went straight to the window. I used the opportunity to import my images and the closed down and re-opened Organizer. The Tabs were again un-responsive.

I found that if I could undock the Organizer window, the Tabs functioned. Problem is to undock the window.

By pressing the Import tab and the un-docking button randomly, eventually the program became unblocked, but unfortunately it activated  in different Import options, from the cloud, from the scanner and sometimes from Files and folders.

I have literally wasted a day.

If the solution is to work only on a single screen this is a retrograde and is non-solution. If I am forced to do this, my Organizing time will double. All my previous versions have supported dual screens. 

I initially highlighted my problem on another forum and MichelB  informed me that the problem had been raised on this forum and suggested that I look for a solution on this forum. 

My frustration levels are soaring. At present, I can't work on 2023, and now it seems my validation of my existing 2018 version has been revoked. There must be a solution, I certainly hope you can provide it for me. 

Thank you
