You are running Phoenix 5.5c while the latest version is 5.6d(real version, check the first post in this thread for confirmation). Anything newer than Radeon Software 21.3.2 is NOT compatible with Phoenix 5.5c.
It's as simple as that, AMD made some significant changes to the drivers starting with 21.4.1.
Im currently using a 6900xt card which is new to me. Before this card I was using BetterHash software. Which was great. I love betterhash.
But I cant seem to use the 6900xt with Phenox miner to mine ETh or ETC. Betterhash has worked with me and we have changed a few settings within Betterhash and also with my Virtual Memory. But nothing has worked. And they suggest to reach out to this form.
For the time being I'm using NiceHash NBMiner and it seems to be working fine. But I want Betterhash
