It does not recover from the freeze, and it can be in any view. I've left it for 6 minutes.
It seems the freeze may be caused by my firewall.
Usually I block Unity when it tries to connect to the internet, unless I need to upgrade Unity or download something from the Asset Store.
When I allow Unity to connect to the internet then it does not freeze when I click Play.
Apologies for adding the attachment in the previous post.
I'll only add attachments in the private support forum.
Thanks for the feedback.
