Lightroom is failing to open properly when Photoshop is running.  Lightroom opens without issue after Photoshop is closed.  

Repro Steps:
1. Launch Lightroom
2. Launch Photoshop
3. Exit Lightroom
4. Launch Lightroom

....  The following dialog unexpectedly surfaces


Pressing the 'Continue Button' at this point does nothing.  The dialog simply reappears.
Pressing the 'Exit Button' closes the app as expected

Pressing "Choose a Different Catalog Button' is successful but I did not want to change catalogs.   Trying to switch back to my initial catalog after going to another resurfaces the above dialog.  So at least in the scenario I have described the user is blocked from opening the catalog they intended to unless they exit Photoshop (I provided quick workaround steps below).

Environment:  Windows 10
Photoshop: 21.0.1
Lightroom Classic  Build:   201910151439-b660523e

Note:  This issue was not occurring prior to my last update of Photoshop and Lightroom.  I found the creative cloud Install.log located in "C:\Program Files (x86)\Common Files\Adobe\Installers" from my install yesterday (11/13/2019) but I don't see a way to attach it to this issue description. 
Let me know if you need the log or any others and i will be happy to supply them.

Pri:   1
Sev:  3

-  It set the pri recommendation high due to the potential visibility of the bug.  You don't want users running into this and it's a simple repro.    

Work Around: 
Exit Photoshop > Load Lightroom > Launch Photoshop.

Seems to be working fine for me with win10. I did have to launch Lr twice after the initial exit though, but i didn't see an error.

I can't repro either, also on Win 10. When LR Classic is closed, is there a .lrcat.lock file lurking in your catalog folder? i.e. alongside your catalog file (.lrcat). If there's one when LR is closed, delete it.
