Versions

I'm using macOS 12.2.1, and atom --version gives

Atom    : 1.60.0
Electron: 9.4.4
Chrome  : 83.0.4103.122
Node    : 12.14.1

apm --version gives

apm  2.6.2
npm  6.14.13
node 12.14.1 x64
atom 1.60.0
python 3.10.0
git 2.30.1

For me Hidden on Startup seems to be ignored in case there is no project folders added to the Tree View.

For me Hidden on Startup seems to work only in case Atom reopens with the Settings tab (still) open.

I'm using Fedora 36 KDE. atom --version:

Atom    : 1.60.0
Electron: 9.4.4
Chrome  : 83.0.4103.122
Node    : 12.14.1

apm --version:

apm  2.6.2
npm  6.14.13
node 12.14.1 x64
atom 1.60.0
python 3.10.4
git 2.36.0

This is a duplicate of #1370.

There is a workaround using a script in this comment.
