dyld Symbol not found

Hi,

on a nativescript project that recently was working perfectly fine to build, I am suddenly getting the following error message during build:

dyld: lazy symbol binding failed: Symbol not found: __ZNSt3__115basic_stringbufIcNS_11char_traitsIcEENS_9allocatorIcEEE3strERKNS_12basic_stringIcS2_S4_EE
  Referenced from: /Users/vmuser/Desktop/myapp/platforms/ios/internal/metadata-generator-x86_64/bin/./objc-metadata-generator (which was built for Mac OS X 12.0)

  Expected in: /usr/lib/libc++.1.dylib

I am using MacOS 11.6.6 and XCode 11.2.1. I already tried reinstalling the XCode tools by doing:

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Please help me. Thank you for your time!
