Hi, everybody This happened to me twice this week. Before and after the latest update.
I don't really know what could be happening. As you might see in the screenshot the library is completely empty but I can still use -and eventually save- the latest brushes in the history.
I even lost the native brushes as well. I tryed to fix it, closing Ps, resiting my PC and of course installing the lastest update but it happened againg today in the same fashion: When I open Photoshop I find I have zero brushes.
It is a little annoying but installed all my brushes again. For the moment it seems to be the only thing to do because I have no clue of what could be causing this issue.
I serched for a similar thread but I couldn't find any.
