title: Xcode 13.2 - Internal error : Missing Package Description Module
body: <p>Just updated Xcode to 13.2 via Mac App Store.</p>
  <p>I installed the additional components, and my project won't compile anymore : Xcode just tells me <code>Internal error: missingPackageDescriptionModule - Resolving Package Graph Failed</code> when attempting to build. None of the Swift packages used within my app seems to build, because &quot;Package resolution errors must be fixed before building&quot;.</p>
  <p>Already attempted to restart Xcode, update macOS, clean derived data, reset Swift package caches and update package versions to no avail.</p>
  <p>Guess I'll try re-installing Xcode but... does anyone else have the same issue?</p>
