Interesting, I am in England and installed KB5030310 2 days ago and I have Copilot.
On the downside if I close MS Edge it can't be opened again until "End Task" is initiated through Task Manager. Then it will open, but fails again to open once it has been closed.
Anybody any ideas on how to fix it?
Update: The problem appears to have resolved itself and MS Edge now opens and closes normally even when Copilot is used.
Further Update: The problem has reappeared. Many times neither Edge or Copilot will launch and I have to go into Task Manager and shut Edge down before it will launch. I have changed it to run with Administrator Privileges but the problem remains.
Does anyone have any ideas on curing the problem?
