Radeon RX 550 Graphic card

Got the latest version 18.1.
Still havin a time of fighting with Defender is blocking it and it not functioning right. Meaning like the allow or not popup thing like back in old Windows. Get it couple time but it doesn't function as like it should -
How to get it to let it allow in the firewall/ Defender ? It take you App section and do not see any AMD. How to get it to stay without repeat and or needing to be fix as may of I'm having some troublesome by it being blocks.
Sounds like your security settings/policies may be overkill or in conflict with other windows settings.
You may want to post a query on 'tenforums.com' to help with that.
