Getting this error when meson setup --buildtype=release . build

Traceback (most recent call last):

PermissionError: [Errno 13] Permission denied: '/home/megatnuar/Downloads/picom/build'

When cd into /picom, there's no build folder. How to continue?

it seems that you have wrong permissions on the picom folder. did you clone the repository as root and trying to build as a regular user?
