Obsidian 1.0.1 won't start

You are not the only one facing this problem. The problem has been reported to the developers already.

In your case, I would recommend to delete (again) your .config/obsidian folder (it should already be enough to delete the “obsidian-1.0.1.asar” file - at least this worked for me), restart obsidian and temporarily deactivate “automatic updates” and “get insider builds”.

What is more, I would strongly recommend to update your installer version to 1.0.0!
