I am using the same but without the full path and threads and this below
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
You must check your antivirus and firewall - usually they stop the miner
configure their exceptions
and if this does not help - maybe you have problem connection with the pool - then try another pool - there are 2 more pools for LBRY mining
try coinmine for example
