(Unknown error) - exit code -1073741819 (0xc0000005)
From BOINC Wiki
Error 0xc0000005 normally means that there are problems with the driver. I'll expect the same issue here, so first try to update your drivers, be it for your motherboard (chipset) or for the GPU that you run work with. Always update the driver from the GPU manufacturer's website, never allow your operating system to update them.
