I was able to build. First, I manually set the version in the project to 4.7.0 for both Apple Watch, Extension and Main app. I got some errors after that, but they seem "random errors" on the builds. Then I noticed our workflow was using "the latest Xcode" which meant Xcode 13.3 Beta 1. Instead I set it to Xcode 12.2.1 I got some random errors after. I tried the build hours later and finally it worked. Since I did more than one approach trying to fix this at a time, I cannot tell what "fix" my issue. I will report later when I make a new build and if I get more info

I tested this in the 13.3 beta (13E5086k) and this issue is not longer happening although I didn't find anything about this in the release notes https://developer.apple.com/documentation/xcode-release-notes/xcode-13_3-release-notes
