Avast suddenly blocks me from casting from pc to any device

[EYEKAY]

Hello,

I just updated my avast premium version program and now i can no longer cast from my laptop to my tv or any other wireless display. The moment i cast, it shows that there is an error but once i disable the antivirus, it connects with ease.

Does anyone know the work around this as i usually cast my laptop screen to an external monitor so that i can view clearly

There is little to work with as error message may (and possibly not) help.

I suspect that this may be Firewall or Network Inspector (Public/Private network) related, not being trusted.

Have you recently had an Avast program update ?
What is your current Avast Prograd version and build number ?

It may be worth checking manually if there is an update available,
