I am having a similar problem, I didn't change any folder location, but when I click open project I can only see recent projects, and when I click import file to load one of my previous saved project, this link open, C:\Program Files\Allegorithmic\Substance Alchemist
but the project folders are not there
all the project files in C:\Users\Pin\AppData\Roaming\Allegorithmic\Substance Alchemist\createdMaterials
folder as json. but I can not open them.
So how can I access and open them?
