iOS location service crash by freezing

We found an issue that make application freezed and then crash on iOS:

void SendDelegateMessage(NSInvocation *): delegate (webView:connectionPropertiesForResource:dataSource:) failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode

This issue happens when enabled “NSLocationWhenInUseUsageDescription” in info.plist and we don’t even have to start location updating. It doesn’t happen on 5.5.0f3, 5.4.x, but in 5.5.0p3, 5.5.0p4. However 5.5.0f3 has other issues (METAL crash), so we cannot use 5.5.0f3 also.

Please help us to address this issues.
Thanks!

[Update] This still happens on the latest version 5.5.1f1.
