When you post configuration to the forum, use the </> code tag to preserve formatting. What you posted above is unreadable without formatting.
If you’re not seeing a log file in the same directory as your YAML, then there’s a problem. Figuring that out is your first step. You may need a clean install. When you get errors, the log will help you find where they are.
Using a good text editor is key. Notepad++ is great if you’re on Windows. YAML cares a lot about indentation. Tabs will break things.
Your formatting for groups is off. Here’s an example from my configuration:
master_bath_lights:
name: Master Bath Lights
view: no
entities:
- light.master_bath_mirror_lights_level_20_0
- light.master_bath_shower_spot_level_21_0
- light.master_bath_ledge_accent_level_22_0
