Your Feedback Assistant report doesn't contain a sysdiagnose, so it's hard to say. Can you create another one and allow it to upload system diagnostics, soon after reproducing the issue? Thanks!

If you file an issue using Feedback Assistant, it should generate one at the time of creating the issue.
