Every solution I open remains permanently locked and inaccessible after closing

I installed Visual Studio 2019 on a second machine today and getting this on every solution I open, rendering it totally inaccessible to me. I see there are other reports of this problem in 2017, which later claimed it was resolved. I don't get this problem on my VS 2019 installation from a few weeks ago...

"An error occurred in 'Solution 'App3' ‎(2 of 2 projects)' while attempting to open 'App3.Android'
The document 'C:\Users\Administrator\Source\Repos\App3\App3\App3.Android\App3.Android.csproj' is already open as a project or a solution and cannot be opened in an editor at this time."

    Further testing on this and I can now reproduce the problem — behaviour differs between VS 2019 16.5.4 on my main machine and 16.6.3 on today's latest installation. It appears to be a bug on 16.6.3.

    If I open the App.Android properties and then close the solution with that tab still open, it locks me out the next time I open that solution, with this rather unhelpful message. However, if I don't keep the App.Android properties tab open and close the solution, it's fine.

    Notable variation in behaviour in the earlier 16.5.4, is that if I leave the App.Android properties tab open, then close the solution, it doesn't even show the tab when I reopen. Therefore 16.5.4 does not exhibit this bug.

    We generally use the later version of VS . And I did a test on my visual studio(v16.6.1) but couldn't reproduce the problem.

    So you can try the latest version of VS.

    Thanks, I appreciate the reply, but our fresh download yesterday gave us a later version 16.6.3 than your version, so your 16.6.1 doesn't appear to be the latest version any longer. Below is the VS - About box for clarification. I can vouch that this behaviour doesn't manifest itself in our last installation which hasn't yet been updated. Presumbly therefore the problem has appeared at some point between your version 16.6.1 and the latest 16.6.3 that we installed yesterday.

    I am sorry, I made a mistake. I have updated my reply . I tested on my visual studio( v16.6.1), but I couldn't reproduce this question.

    Besides, have you tested on the latest version of VS(16.6.3)? Is there a problem with the latest version?

    Thanks for the reply. Yes, I'm able to reproduce the problem every time on VS 16.6.3, which is the version shown in my "About" screenshot and in yesterday's examples.

    If your version 16.6.1 is fine, then this problem has really just begun very recently.

    Sorry, I updated my VS to Version 16.6.3, but the problem cannot be repeated.

    Could you please share your detailed steps and screenshots with me?

    It's straightforward to re-produce, as follows. Incidentlly I updated from version 16.6.3 to 16.6.5 today. The bug is still present, though it isn't present on the earlier 16.5.4.

    • Open Visual Studio 2019
    • In the "Open Recent/Get Started" dialogue screen, chose the lower box Create a New Project
    • Select Mobile App (Xamarin.Forms)
    • Click Next
    • Name : MyApp
    • Click Create
    • Remove the tick from IOS, leaving only Android selected
    • Select Blank template
    • Click OK and wait for the solution to be created
    • In the solution explorer, right-click the project MyApp.Android, then choose Properties from the context menu
    • Leave this dialogue open (leaving the solution open on this page demonstrates the bug behaviour and I think you were not opening this when you tested it yourself)
    • Click File - Close Solution
    • In the "Open Recent/Get Started" dialogue screen, single-click MyApp to re-open it. Then you see the following.

    It isn't a problem that can't be circumvented, I should add, and I don't think it necessary to spend further time on it. Originally we thought our project was damaged, but in fact this isn't the case. We can simply close the dialogue above and there's no problem with that. However, it was quite disconcerting.

    Yes, I reproduced this question according to above steps.
