Error in Xcode

I was trying to debug webkit with IOS simulator, but it crashes on start.
I followed instructions from this article. https://engineering.salesforce.com/debugging-webkit-in-hybrid-mobile-apps-2eee63a4c922.
Xcode attaches to all required processes, but before initial page from bundle is rendered, com.apple.WebKit.WebContnet process fails with EXC_BAD_ACCESS (Code=2).

- MacBook Air (M1, 2020)
- macOS Big Sur 11.5
- Xcode 12.5.1
- Simulators with iOS 14.5
- WebKit's master branch
- Test application: https://github.com/mmafrar/swift-ios-wkwebview-demo

I execute following commons to get sources and build them:

git clone git://git.webkit.org/WebKit.git WebKit 
cd WebKit
sudo Tools/Scripts/configure-xcode-for-embedded-development
./Tools/Scripts/update-webkit
Tools/Scripts/build-webkit --ios-simulator

Then I selected WebKit scheme, change paths to relative and selected test application to run. Before first page is rendered, process crashes.
The same scenario works for others with MacBook on inte
