My CL is almost definitely unrelated, it just changes some time values unrelated to this stack. From the stack, it appears likely that WebLocalFrameImpl::FromFrame is returning nullptr at https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/aom/computed_accessible_node.cc?l=87&rcl=04add8c6cd47cbac836956d9db9d15ea64d34855

It looks like the person who landed this code has left, so cc the reviewers from https://chromium-review.googlesource.com/c/chromium/src/+/931301 to see if they know who should own this.
