Cannot launch Android Studios default "new flutter project" on iOs

Issue

I have recently updated multiple components of my system and since then flutter iOS builds don't work anymore.

My plan was to identify the libraries that cause the problems I decided to start with a clean new project and add my required libraries one by one until it fails. The problem is that I cannot even launch a freshly created Android Studio "new flutter project" on the iOs Simulator (or on a real IPhone for that matter).

I have added signing in Xcode 13.2.1 - no further changes.

My system runs on macOS Monterey 12.2.1.

When I try to launch this "virgin" app the Output is:

What am I missing?

Solution

Turns out, I have updated something in my conda base environment that caused the issue.

A conda deactivate was sufficient to successfully run flutter.

To make the run button work again I had to disable the automatic start of the conda base environment by adding conda config --set auto_activate_base false after the conda init block in .zshrc and restarting the MacBook.
