CSUserQuery Generating Model Load Failure - No Results

I'm trying CoreSpotlight on the 18b1 seed on iOS and after submitting my query, I'm getting multiple errors about what looks like missing models:

[Model loading] model loading failed with err -1000 for model path /Users/hunter/Library/Developer/CoreSimulator/Devices/0AF4F46E-5510-4458-B61C-F8A153155809/data/Containers/Data/Application/1D8580C0-AC80-4949-9FDA-31DB463BDA5C/Library/Spotlight/Resources_V3/Default/models/spotlight_l2.mlmodelc and directives path /Users/hunter/Library/Developer/CoreSimulator/Devices/0AF4F46E-5510-4458-B61C-F8A153155809/data/Containers/Data/Application/1D8580C0-AC80-4949-9FDA-31DB463BDA5C/Library/Spotlight/Resources_V3/Default/directives/directives_l2.mdplist

I am calling CSUserQuery.prepare() but that doesn't seem to make a difference.

Is there more to this than what is on this page? https://developer.apple.com/documentation/corespotlight/building-a-search-interface-for-your-app?changes=latest_minor

Still seeing this with seed 2. Anyone got this to work?

Same with seed 3.

Same on beta 4. Btw running on device does not trigger such errors. Instead it complains about connection to some helper app:

### qid=1 error Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application." reply:<xpc object>
