Flutter app can run in Xcode and not in Android Studio - ios

Question

As the title suggests, I simply cannot run my flutter app on Android Studio (using the IOS simulator). Somehow, if I run and fix all Xcode errors in Xcode itself, I am able to run it.
However, when I try to run it in android studio a second later, many errors appear coming from the IOS build. There is no specific error log as the warning are always different.
Here are some of the causes that I am suspicious of:
I updated to Xcode 13, which has a new build system.
I updated to a new Flutter version.
I updated to a new Android Studio Version (Arctic Fox).
I have tried many things, including:
Pod deintegrate** & pod install
Cleaning and running
Restarting the computer
Legacy build system

There are just too many things I have tried, I only remember half of them. Here is my latest error log when trying to build from Android Studio:

Here is my most recent error log:

Could not build the application for the simulator.

Solved after a month
The only truly important error was the following:
ld: building for iOS Simulator, but linking in dylib built for iOS, file '/Users/tomasward/Desktop/Fredi/ios/Pods/TwitterKit/iOS/TwitterKit.framework/TwitterKit' for architecture arm64
What is it actually saying?
arm64 is an architecture used for physical devices, not for the simulator. So, I was trying to simulate an invalid architecture in a virtual device.
I had read that I needed to exclude arm64 from my build settings in my target project. However, the missing step was to also exclude it from pods as follows:
Voilá!
