HP notebook does not connect to Microsoft Wireless Adapter P3Q-00019

[MUJBR]

The Microsoft Wireless Display Adapter (MSDisplayAdapter_22) is recognized and connectable by any device here, except my new HP Notebook. Android phone - to - Sony projector => OK ,connected. Android phone to LG Smart TV = > OK, connected. By clicking "Action Center -> Connect -> I see the wireless display device "MSDisplayAdapter_22". In the projector or the Smart TV I see "MSDisplayAdapter_212 - Ready to Connect". When I click "Connect" in the laptop, I see the TV Screen changing to "Connecting to <mycomputername>". After a while (30s+-) the laptop display an yellow text with "Couldn't connect". I've spent HOURS, DAYS on MS troubleshootings guides, drivers updates, Windows 10 updates, Firewall, 2,5 G, 5 G, NW adapters in device manager, I'm tired. What did I miss? Is HP the only one unable to connect? Any help here?

The problem was in AVAST Antivirus Firewall setup. I noticed that shutting the f***  Avast firewall down the connection succeeded. So set Network Profiles that the adapter wants to use to "Private" (it borns as "public"). In the example below the adapter was trying to use the network profile "DIRECT-MUJ-HP03MCTV", originally as "public". When I changed to "Private" the adapter connected even with the Avast Firewall ON. But BEFORE this action, go to "Protection" -> click on "Applications Settings", open group "Microsoft Corporation",  find "Windows Driver Foundation" and click on the orange bars to assure all five bars are ON. Easy? Enjoy, it costed me a weekend of confusing emotions related to f***** technology.
