New version is blocking Windows 11 Miracast Screen Sharing to TV

Running latest version of 360 for Windows 11 home.

Miracast screen share only works if I disable Norton.

Can somebody please help me get this working again - only a problem since the new version of Norton installed - nothing on my network has changed.

Small update:

Tried using a rule to allow full net access to “C:\Windows\System32\WUDFHost.exe” — which is what Miracast evidently uses to cast - and it still does not work.

Only thing that works is turning off Norton.

Same here; worked before; now must disable Norton.

I wound up restarting my PC and now Miracast doesn’t work at all. Even with Norton disabled.

These problems all started with the new Norton. Absolutely frustrating - especially when you are paying for this stuff to work.
