Happened to me as well. Exactly the same as described. For me it happened on two different projects as soon as I started adding scale effect animations. I'm using Xcode 13.1 on Monterey 12.0.1. (M1 mini 2020 8gb). Tried the rosetta workaround, didn't help.
I hope Apple fixes this soon or at least informs us about the exact cause so we can find a reliable workaround.
