you really didn't check your con file
now you mis here comma
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"shaders" : "0", <-
"gpu-threads" : "4",
it is logic where comma must be and where not
i already tried to remove the comma and run the miner, and i already also tried to put comma and run the miner. both have the same result.
