When I have a part open, right click material in the tree, and select "Edit Material" it takes more than 30 seconds to open. And when I'm done selecting my material it takes another 30 seconds to close. If I select a material from the favorites list it applies it immediately.
I'm on a 2019 Student Premium install and don't have any extra materials installed. The installation is on an NVMe disk.
Does anyone know why it takes this long to open and close? My work copy (2019 Standard) is immediate.
