Can't install Bitdefender Total Security Antivirus (MacBook Pro 2017 running MacOS Catalina 10.15.5)

I can't install Bitdefender Antivirus on MacBook Pro 2017 after upgrading to MacOS Catalina 10.15.5

The Installer say installation is completed. After closing/quitting the Installer, a small window popped-out. It says Downloading Antivirus for Mac. But nothing happened, nothing was dowloaded. Progress bar stayed empty. And then the pop-up window disappeared.

Inside the Applications folder / Bitdefender: There's only an alias to BitdefenderUninstaller. Nothing else is in there. No Bitdefender application.

I tried every troubleshooting methods that are suggested here, over and over again:

and here:

But still. Nothing worked.

Can somebody please help me?
