For a large / older iOS app project, we have noticed the the view hierarchy debugger works fine for our UIKit screens, but runs into the following crasher whenever we try to launch the view hierarchy debugger on a UIHostingVC screen with SwiftUI content:

Unable to capture the view hierarchy "AppName" encountered an unexpected error when processing the request for a view hierarchy snapshot.

--
The operation couldn’t be completed. Log Title: Data source expression execution failure.
Log Details: error evaluating expression “(BOOL)[[(Class)objc_getClass("DebugHierarchyTargetHub") sharedHub] performRequestInPlaceWithRequestInBase64:@"..."]”: error: Execution was interrupted, reason: EXC_BAD_ACCESS (code=2, address=0x16b23bff8).

Has anyone successfully resolved the underlying issue in this crasher? Tried all the typical recommendations for a clean build, clear derived data, use the "Debug -> View Debugging" menu - all with no resolution.
