I´m a Revit user since 2006 and I´m having a strange behavior with Revit versions form 2020.
I can use Revit for modeling, but any version from 2020 material editor simply doesn´t open.
On my notebook I´ve already worked with 2016, 2017, 2018, 2019, but it is not runing newer Revit versions.
I can run Navisworks, Autocad and even Recap, but can edit materials in Revit.
