[REQUIRED] Please describe the issue here:

After Updating firebase to the latest version 11.8 ,
Xcode fails to build our project during the final linking stage
I thought maybe its some conflict with some other sdks we have
so I removed all the sdks and kept only firebase which failed to build
Since the error mentioned Firestore related errors , I removed Firestore from the project and commented out all the code which used Firestore and it SUCCESSFULLY built in Xcode

after which I decided to just included Firestore only in the package manager and not have any Firestore #includes
in the code.
This Project also Built SUCCESSFULLY
However when I used any firestore code in the game
the subsequent export FAILS to build.

what's very peculiar to me is that
this issue started occurring to me after a specific time

on 20th March around 1PM IST I was successfully able to build the whole project with the latest 11.8 version
but after 3PM onwards the same project fails with the below error

I have tried firebase versions from 9.6 as a way to downgrade and just get the project to build to meet our business goals
but to no avail.
We are STUCK.
We are not able to move forward.
Kindly be of assistance.

Only Android Builds work.

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
What's the issue repro rate? 5/5

What happened? How can we make the problem occur?
I started getting this error on Xcode during the final linking stages

After googling and searching on the Issues here I understood that this was fixed and then I Updated to 11.8 version
after which I started getting the below error during the final linking stage in Xcode
