Crash due to an assertion in libswiftCore

[low-batt]

On my MacBookPro18,2 running macOS Ventura 13.2.1 and Xcode 14.1 I happened to bring up Console and found 6 swift-driver crash reports. They all seem to be due to an assertion in libswiftCore. I have no idea what triggered these failures. I tried to reproduce the crash but was unable to do so.
