Clicked on 'send now' for roughly 10 crash reports but there is no sign of progress these are actually sent. The setting is to automatically send crash reports to Brave, not sure what this implies.

the root cause is still somewhat uncertain
the changes made were for user.max_*_namespaces which were to all appearances at an excess value of 119431 and for user.max_user_namespaces lowered to 16000
after clearing the user.max_user_namespaces setting and letting the system decide this is now back at 119431 but brave appears to function without exit or crash.
it does appear possible there are one or two url which instigate the unexpected stop for brave-browser but these have yet to be identified, possibly correlation not causation
