Since updating to macOS Sonoma 14.1 and Xcode 15.0.1 I get the following error message:
Build service could not create build operation: unable to load transferred PIF: The workspace contains multiple references with the same GUID 'PACKAGE:1YUBE3S3A43QP92YAIBS0U5OJYK9I2OP2::MAINGROUP'
I do not know how to solve this problem. Even a fresh install of macOS Sonoma does not work.
