I have the same problem, even though I added the app to firewall exceptions as instructed. Also, most of my games are running underpowered with performance significantly worse than my 6year old card. Even if I force the card to use 60-70% Hz through Adrenaline, the power consumption is still low. I have the latest drivers having just bought a Sapphire Pulse Rx 5600 XT.
I have also managed to solve the problem of underpowering for Witcher 3 by turning VSR on and running the game at 4K (current screen is 1080p 144hz, but running at 60hz over hdmi as it doesn't have a dp port). So, it runs 5x better at 4K than 1080p!!!
