Rhino 7 updates, can't edit materials anymore!

Hi, I just updated my rhino 7

Version 7 SR37
(7.37.24107.15001, 2024-04-16)

when I click on the material tab in the layers editor I am not able anymore to edit them

Is this a bug or am I doing something wrong?

hello @revink pls run _SystemInfo in Rhino and post back the (full) results.
I can’t repeat that issue here.
