Can't install from any dmg files on Macbook Air

I am trying to install vlc player from dmg file and it is not getting installed.

I checked the file using disk utility and there was no error in the file.
When i try to install, a warning screen is shown saying,
I tried installing the dmg through FastDMG app also. It also did not work.
When I am trying to install from terminal, the following message is shown.

hdiutil attach vlc.dmg

hdiutil: attach failed - Device not configured

I tried installing other player like IINA from the respective dmg files. Same error is being shown.

MacBook Air 13″, macOS 10.15

Where did you download VLC from? you should download it from their site…

https://www.videolan.org/

Once downloaded, all you should have to do it double click on the dmg file then drag VLC over the Applications folder.

Try safe mode, see if it helps.

How to use safe mode on your Mac - Apple Support (Takes longer to boot)

Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.

Actually you never said the dmg wouldn't open. You said you couldn't install the dmg. But thanks for clarifying.

Thanks for posting this. I'm not sure that reinstalling MacOS is a viable solution for me as I am seeing this issue on several production machines. Might we pursue a solution that addresses the problem directly?

To be clear, are you reinstalling over the existing installation or erasing the partition first?
