Visual Studio 2019 Community Edition Installer can't start

Question

I tried to upgrade my Visual Studio 2019 Community edition, but the Visual Studio Installer can't start.

I tried a lot of things including uninstalling the existing version, using offline version, etc, but now I end up with no working version of Visual Studio.

This is the log from bootstrapper:

I hope someone can help me find the solution.

There can be some troubles with the certificates on vs_installer.exe and vs_installershell.exe. Installing this KB3004394 may help.
