Any workaround to M1 crashes initializing a WkContentRuleListStore

We purchased M1 Mac mini hardware to run our pipelines, however, we get a crash whenever running on IOS13 simulators using Xcode 12.X when trying to initialize WKContentRuleListStore.

The crash does not happen on Intel hardware nor on M1 with IOS14 simulators.

The storeUrl is initialized as follows:

Code Block
let storeUrl = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true) ?? FileManager.default.temporaryDirectory


The temporaryDirectory is not being used, storeUrl resolves to the doc directory as expected. When calling:
Code Block
WKContentRuleListStore(url: storeUrl)


The following stack trace is observed:
