Logging in doesn't work

[GeorgelPreput]

After having installed Steam, and ran it (but never logged in through the GUI), there is a config.vdf file to read, but it has no 'Accounts' key. This will trigger a failure on line 276:

          username = list(vdf.parse(f)['InstallConfigStore']['Software']['Valve']['Steam']['Accounts'].keys())[0]

If afterwards you remove the config.vdf file, or at least rename it to something else, the following crash occurs when running steam-cli login:

Traceback (most recent call last):
File "/usr/bin/steam-cli", line 33, in
sys.exit(load_entry_point('steam-cli==0.0.0', 'console_scripts', 'steam-cli')())
File "/usr/lib/python3.9/site-packages/steam_cli.py", line 765, in main

My config.vdf has the subkey Steam but written in lowercase, so when I use it like

username = list(vdf.parse(f)['InstallConfigStore']['Software']['Valve']['steam']['Accounts'].keys())[0]

there is at least no exception, but it will hang indefinitely on the login response from the Steam server.
