Could you try to run cuda-memcheck with your input address file ?
"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.0\bin\cuda-memcheck.exe" VanitySearch119.exe -gpu -r 1000000 -t 0 -g 320,256 -o found.txt -i 50.txt -stop
After about 3 minutes, there is an error, this is with 100 addresses (-i inputfile). There was no error with 50 addresses. With 500 addresses, an error occurs after a few seconds. We are talking about full bitcoin addresses (example: 152hx7Sp822qqWSPHRbK7b8cKdAaPzALqd)
What you do makes no sense at all.
