Loading problem Brush tool and Photoshop

Hi,

I am facing two problems.

1: I work a lot with the Brush tool in Photoshop. But regularly my Brush tool crashes and keeps loading. Photoshop does not respond anymore, even saving the file fails.

2: Photoshop does not want to open anymore. The icon keeps loading. Eventually it indicates that the program is not responding.

I use Photoshop version 23.1 and MacOS Big Sure version 11.2.3

I hope someone can help. Thanks.
