Visual Studio Community 2019 keeps crashing upon installation

Question

I've downloaded the installer today, then I executed it, it downloads some data, installs something, and then crashes on the window "Almost done... Getting everything ready". After that the installer results to be installed on my machine, but If I try to run it, it opens the windows, I can see some "loading" animations and after 1 second it freezes and then closes. I've tried several times to start it with the same result. I've already tried to update the system (restarted), disable the antivirus, and run as administrator, nothing did help. Going to the event viewer I find this error:

In the past I had VS community installed on this machine, it shouldn't be related to a hardware issue.

Is there anything I can try to solve this problem?

Answer 1

I've managed to have the installer working. I've noticed that as the installer starts it looks for updates and there is where it freezes and crashed. I've disconnected my laptop from the internet and then started VS installer, it didn't crash. Once moved to the "Available" tab, I've reconnected my laptop and now I'm installing Visual Studio.

Answer 2

Same error and same "solution"

Answer 3

Hello

Looking at your names. it seems you're all Italians, like me.

  Exception:
  System.FormatException
  Stringa non riconosciuta come valore DateTime valido.
  System.DateTimeParse.Parse(String s, DateTimeFormatInfo dtfi, DateTimeStyles styles, TimeSpan& offset)
  System.DateTimeOffset.Parse(String input)
  Microsoft.VisualStudio.Setup.Installer.DeveloperNews.ViewModels.NewsFeedItemViewModel..ctor(NewsFeedItem item)

There should be a nationalization related bug causing these crashes, on a date conversion occurring while updating the news feed, do you know how to notify Microsoft about it? So we can get a working installer with the next releases.

Thanks
