After updating drivers from 19.9.1 to 19.9.2 miner won't start, claymore works fine.
Check that windows defender isn't blocking the process... that's what happened to me.
Yea, i've read it. But windows defender was always turned off. I'm using 3-rd party AV and firewall, but they didn't do anything, i've tried to turn them off too, but it didn't help. Also no updates were installed, nothing else changed, only new drivers installed after DDU cleanup. Still trying to figure out what is wrong.
