Short description of error
I was trying to install addon test.py
from here: https://docs.blender.org/api/current/bpy.types.AddonPreferences.html

And now whenever I go to the addon preferences

I'm getting next error

Traceback (most recent call last):

    raise ValueError('malformed node or string: ' + repr(node))
ValueError: malformed node or string: <_ast.Name object at 0x0000014F702D1448>

Reinstall Blender did not help.

Probably it has happened because of this string bl_info = {"name": __name__, ..., but how to fix it now?

I would suggest you open C:\Users\[your username]\AppData\Roaming\Blender Foundation\Blender\2.90\scripts\addons and delete the test.py in that folder.
