Command PhaseScriptExecution failed with a nonzero exit code

Hi,

I have a project written in Swift 4 and the following pods are being used in the project:

'GoogleAnalytics'
'GoogleMaps'
'GooglePlaces'
'CarbonKit'
'Firebase/Core'
'Firebase/Messaging'
'Fabric'
'Crashlytics'
'JGProgressHUD'
"QBImagePickerController"
"YoutubePlayer-in-WKWebView", "~> 0.3.0"
'TrustKit'
'SwiftDate', '~> 5.0'

When I am trying to build the same code in XCode version 11.3.1 (11C505), it’s working fine. 
But the same code when I am running in XCode version 12.4 (12D4e), it’s showing the following error:

I am unable to find a solution for this. Please help to resolve this issue.
