Multiple Commands Produce gRPCCertificates.bundle error on Archive (iOS Xcode 11.1, Firebase SDK)

In updating to the latest Cocoapods, I updated googleapis pod and encountering the following error on Archiving the build in Xcode 11.1:

Multiple commands produce '...iphoneos/gRPCCertificates.bundle'

1) Target 'gRPC-gRPCCertificates

2) Target 'gRPC-C++-gRPCCertificates

How do I remove the Build target gRPC-C++ certificates? Looking in Build Settings and can't seem to find anything here.

Here is my Podfile:

# Uncomment the next line to define a global platform for your project
# platform :ios, '13.0'

target 'Kintsugi Mindful Wellness' do

    use_frameworks!

    # Pods for Kintsugi Mindful Wellness
    pod 'Firebase/Core'
    pod 'Firebase/Auth'
    pod 'Firebase/Firestore'
    pod 'Firebase/Database'
    pod 'Firebase/Crash'
    pod 'Firebase/RemoteConfig'
    pod 'Firebase/Storage'
    pod 'Firebase/Performance'
    pod 'Firebase/Functions'
    pod 'Firebase/Messaging'

    pod 'googleapis', :path=> "."

    pod 'GoogleSignIn'

    ...

    target 'Kintsugi Mindful WellnessTests' do
        inherit! :search_paths
    end

    target 'Kintsugi Mindful WellnessUITests' do
        inherit! :search_paths
    end

end

Older thread mentions updating to the latest pod (https://github.com/firebase/firebase-ios-sdk/issues/2102) but I've already done so and keep encountering this issue (happens every OS update but keep forgetting where to change this config).

When I use the Legacy Build System, I get more granular errors as follows:
