Actual results
There are crashes: b/464096258
Code sample
On file AccessibilityBridge.java, in line 992, there is a recent change:
assert embeddedView != null;
// The embedded view is initially marked as not important at creation in the platform
// view controller, so we must explicitly mark it as important here.
embeddedView.setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_AUTO);Note, the assert is usually ignored in production build. Here we should do an if condition check, just like other places, for example, line 1643 and line 2031.
I suggest the code to be:
if (embeddedView != null) {
// The embedded view is initially marked as not important at creation in the platform
// view controller, so we must explicitly mark it as important here.
embeddedView.setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_AUTO);
result.addChild(embeddedView);

This should have been fixed by #180539. Please let me know if you experience otherwise. Also will cherry pick the fix to beta/stable.
