Quick Share for Windows - black screen

[Members_Xc3qaKR]

Hello,

End April/begin May this year Quick Share from Google (previously named Nearby Share) stopped working on my computer (Windows 10). Before that I transferred files to/from my pc and my Samsung Galaxy M20 numerous times without any problems. Now, when I start the app on my computer,  a solid black window appears. 
 
I posted a question on the Community for Android forum, moderated by Fred JR (the topic can easily be found by searching for "Quick Share from Google not working - black app window"). After following a number of repair options suggested by Fred without success, he eventually referred me to Samsung developer support. 

I sincerely hope  a solution for this problem can be found, as I loved this app.

Hallo Members_Xc3qaKR,

Our Product Specialist asks if you checked on your PC Settings ---> System ----> Shared experiences ---> Check if Nearby Sharing is turned on ---> Check if 'Visibility' is set to 'Everyone nearby'.

After this does the app still shows a black screen?

Hello Ajay,

Is there any update on this issue from the Product Specialist? 
BTW, I have an addition to make to the in formation shared earlier: Even though the black screen appears on my desktop I am able to send files from my (samsung) phone to my desktop (while the black screen is on).  Visa versa is not possible, as, due to the black screen, I have no  interface on my desktop to search for and select the target device.  See enclosed pic.

Hallo @Members_Xc3qaKR,

Our Product Specialist ask if you also share the full modelcode and Serialnumber of your M20 through a private message. When I received it I will send it to her.

Hello Ajay,
Attached screen copies from the Droid Info app, (hopefully) containing the details the product specialist is asking for. 

BTW, i don't quite get why her attention is focusing on the mobile device, as the problem is obviously on the desktop PC...

Kind regards,

Hi @Members_Xc3qaKR, thank you! I will send the screenshots to the specialist and hide them afterwards, since @Ajay-A asked to receive the information in a private message. 

Kind regards,

Hello Joey,
Surprise, surprise!  All of a sudden, but after  Windows updates  rolled out and installed on October 12 and 13 the black screen has not returned anymore. I now have the normal Quick Share UI window on my desktop computer. 
For your information, the following updates were installed: 

Assuming that the Quick Share app for Windows is built with the .NET library, I have the feeling/suspicion that the app now  working has to do with the .NET Framework update, about which Microsoft states the following:

It would be nice if you could verify this. 

Kind regards,
Gijs
