Could not load all the brushes because the maximum number of brushes have been loaded.
I have an older version of Photoshop (2015) on my computer wich works fine. But when I import my old brushes into my latest version of Photoshop, he has a problem. I receive a message described in the title.

I have 57 folders with brushes and in each folder there are +/- 400 brushes for a total weight of 1,39 GB.
What I did is erase all existing brush folders and imported the old one ones but the last 4-5 folders he could not add for some reason.
How to remove this cap?
