I had the same issues, this past week.. the 3.0 versions gave my 2 rigs massive problems. It just wouldn't start and kept crashing.
I've switched back to 2.9 on 2 rigs and claymore on my nvidia mining rig (nvidia on phoenix kept locking up the rig).
Hello
I needed to install the drivers new. I use -amd. I use RX480, blockchain driver and 3.0c. Stopped working last friday.
FATAL ERROR: Debugger detected
What can I do? Claymore is working.
Thx for helping
