That is a very old prerelease. The 12.1.0 release version has a date of March 14, 2020.

Thanks Szabolcs, $Version says
12.1.0 for Microsoft Windows (64-bit) (July 23, 2019)
I was sent this 2 weeks ago by Wolfram for evaluation. And it is failing!
The reason why I asked is that this exact bug was present in one of the early prereleases, but it was already fixed 8 months ago. If you have a prerelease, you should upgrade to the final version. Generally, it is not a good idea to rely on prereleases as they are expected to have bugs, including crashes, which you complained about in your other question: https://community.wolfram.com/groups/-/m/t/1933586
Is there some magic update I need to apply?
What version are you using? What does $Version return when you evaluate it (please post the output, precisely as it is shown)?

Dear all,
I cannot reproduce that issue either.
You can try this procedure:

Thanks Mariusz, but no it is still the same. It is the same if I close and re-open Mathematica and then open Histogram in the help system and execute the examples.
For me works fine. Maybe execute this:
ClearAll["`*"]; Remove["`*"];
and try again.
Regards M.I.
