flutter upgrade - failed to create a directory at "/Users/.../.config/flutter". - Flutter Daemon has terminated

after upgrading flutter on my Mac the "flutter doctor" command doesn't work because of "failed to create a directory at "/Users/Michael/.config/flutter". The flutter tool cannot access the file or directory."

Why I get this message and why I can't debug anymore: "The Flutter Daemon has terminated. Cannot launch without an active device" ?

Before "flutter upgrade" the "flutter doctor"-command worked (with and without sudo):

flutter doctor -v

After "flutter upgrade" I got the following message because of missing permissions (but I am admin and owner of flutter-directories):

When I now run "flutter doctor -v" I get the same failure "failed to create a directory at "/Users/michael/.config/flutter".

When I run "sudo flutter doctor -v" I get:

Woah! You appear to be trying to run flutter as root.
   We strongly recommend running the flutter tool without superuser privileges.

Why I get these failures since "flutter upgrade" and why I can't debug anymore: "The Flutter Daemon has terminated. Cannot launch without an active device" ?

flutter upgrade permissions

Run this command in terminal:

sudo chown mohittanwar /Users/mohittanwar/.config

That solves my problem... Note: Use your own system user name.

I also had the same issue, but got solved when I did the below steps.

sudo flutter downgrade

sudo flutter doctor

sudo flutter upgrade

sudo flutter doctor

I had error when the flutter upgrade was done, but got solved when I ran flutter doctor.
