Tested the above file. Everything works as expected in the todays build.
Opend the file.
Only changed a few small things in the scene. Lowered the Cryptomatte Levels to 2 because as I know you only need a higher level if the object/material count reaches a limit so not all matte infos can be stored on one cryptomatte layer.
Added a reroute node to connect the viewer an the composite nodes.
And I set the View Transform in the Color Management tab to Default, otherwhise you don´t get a real black/white mask. You can try, set it to Filmic and see how the mask gets grey.

Maybe try my blend file:

You only have to render the animation. Its set to one frame.

now I have an conclusion.
the problem is Filmic it will push light tint color to white.
and on the problem file unfortunately random generate color all are light so filmic push it all to white I tried to adjust the curve and could see that Cryptomatte is always there we just cannot see it.
so to use CrpytoMatte it is better to use default color mode.
some point of curve will cut the color out to white not sure its a bug or just how filmic is work.
