I downgraded to v1709 to see if that would help... Trying at stock settings... The miner crashes...
POSIX WinThreads for Windows has stopped working.
This is a long shot, but we're aware of a corner case where the init phase could still be problematic with multiple Polaris cards. It would still report the initialization was ok. I have a fix that will be released in the next version. To check if it is applicable, can you post the output from the start until the crash you're seeing?
