Help me here on a most weird problem.
I have a Ryzen 1700 machine, with 16 Gb RAM and 3 Ellesmere cards that refuses to mine RandomX.
It already mined it fine, then XMrig and xmr-stak just exited.
I thought it was a config problem, so I copied the config.json and edited address and walet and it started mining it no problems at all.
Today I rebooted because a card wasn't sending shares, and now I can't mine.
It just exits, sometimes sends one or 2 shares and then exits.

No warning, no nothing.
XMR-stak displays a similar behaviour.
I disabled Windows antivirus, added an exclusion to folder, system is stable, I tested with memtest and prime 95.
I have one more 1700 and a 3900x and it works just fine, no issues.
