Thanks for the screenshot. Would it be possible to share one of the experiments using the menu File > Export as Archive?
To help understand the issue, could you also please let me know what log messages are output by Console.app? You will find Console.app inside your Applications folder, under Utilities. If necessary, please select the item ‘system.log’ in the sidebar on the left. You can filter out messages using the search field and the query ‘findings’. For older messages, you have to load them explicitly by clicking the “Earlier” button. You can then select the messages in the window, choose the ‘Copy’ menu item (cmd-C) and paste the text in your email (please do not send a screenshot of the Console app, it usually trims part of the messages).
Note that this is a public discussion, so it would probably be best to send that info via email to email@example.com
Thanks for your patience and help!
