@npaschke1 check this https://github.com/CocoaPods/CocoaPods/issues/12456

in the comments you can find someone replace PBXFileSystemSynchronizedRootGroup with PBXGroup

[npaschke1]

thank you. found a workaround in PBXGroup attempted to initialize an object with unknown ISA PBXFileSystemSynchronizedRootGroup #12456 the replace didn't work, but was able to use another comment to resolve.
