There are a few things you can do to troubleshoot Photoshop brushes not working. The first is to make sure that your Photoshop software is up to date. If it isn’t, you can update it by going to the Adobe website and clicking on the " Updates for Photoshop " link. Once you have updated your software, try again using your brush. If that doesn’t work, then you may need to get a new brush or update your Photoshop software.
