dr 20 Voice Training download fails

On DR 20.0, when using "Extras Download Manager" AI Voice Training within a few seconds the manager goes from "0%", "56%" "Installing" then "Download Failed". Rebooting does not help.

Was able to do so with beta 4.

How do I reset the download process?

Is there a place where I can clear out the prior, failed download and start again?

Thanks.

For Windows. the location of the Voice Training extra is in the hidden directory:

C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\Extras

I renamed the Extras folder and started DR again and was able to download the Training extra and to use it.

Side note: For what ever reason, if my ethernet is set to 1 Gb speed, quite often downloads from BMD, like DR Studio or DR Extras, fail. If I cap the speed at 100 Mb (via control panel, etc.) then downloads are more successful.
