I have the same issue. Went through all the steps in the README.
Flutter 3.3.9 • channel stable
flutter_unity_widget version 2022.2.0
Unity version 2022.1.13f1 and 2022.1.7f1 with fuw-2022.1.7f1.unitypackage

@CaroloFa
Are you getting the exact same logs, or just a crash on startup?
Recent crashes on startup are usually caused by the Xcode 14 Thread Performance Checker setting.

Regarding the original issue here, I cannot replicate it by using the mentioned settings.
Just a wild guess but looking at the newer crash, it might be useful to look into Xcode settings as well.

[CaroloFa]

I'm not sure if it was the exact same log anymore, but it was definitely very similar.
I managed to make it work. I guess there was a generel problem with podfile in the workspace setup. Simply disabling the thread performance checker setting was not enough.

I did something like this:

• run pod update in ios/Pods
• delete podfiles
• flutter clean
• flutter pub get
• flutter build ios before opening ios/runner.xcworkspace
• made sure everything was setup correctly according to the readme
• Did this App crashes on iOS16 with Xcode 14 #703

When this occurred to me it was due to forgetting updating the ios/Runner/AppDelegate.swift file
