After upgrading to both the 18.2.3 and the 18.3.1 drivers I haven't been able to open Radeon Settings. After boot, I don't get the Radeon icon in the task tray, and if I have task manager open while I try to open Radeon Settings I see RadeonSettings.exe start and quickly die. I have tried the clean install option, the AMD driver cleaner, and DDU, all with the same results. I've needed to revert back to 17.2.2 to gain access to Radeon Settings. I have reported this on the "issue reporting forum" as well.

Did you run DDU from safe mode? It makes a difference. Run DDU and restart to normal. Run registry cleaner, I use CCleaner as it is very safe, to remove orphans left behind after DDU. Reinstall latest driver with Custom not Express install and choose Clean Install. It makes a difference. Hopefully this gets you going. I also have a RX 580 and didn't get the Radeon Settings in notification area with the first Adrenaline Drivers, this fixed it for me.
Just attempted, same result. Back to 17.12.2 I go.
** Windows 7 and Windows 8.1 must be fully updated before attempting to install any AMD driver. All 'critical', 'recommended', and 'optional' (no language packs,etc) updates as well as any Service Packs (SP) must be installed before any attempt to install graphics drivers. If you do not get this message .... keep installing until you do:
The only update I haven't installed is the preview of monthly quality rollup KB4075211. I'm up-to-date as of KB4074598. Thank you, but this wouldn't seem to be the cause.
EVERY SINGLE AMD DRIVER UPDATE DO THE FOLLOWING:
1) Run 'regedit' ; HKLM/SOFTWARE/AMD/CN - Driver Version. Delete the number that you find, close registry & reboot.
This will allow you to open the stuck on tray driver settings, re-occurring Chinese Bug.
2) Run 'regedit' ; Find "ULPS", set all entries of 'EnableULPS' to 0. When done close registry & reboot.
This will remove the sleep mode for a 2nd or 3rd GPU if you have them, temps & run clocks will display normally.
(Until I find otherwise, this is my M.O. from now on.)
