The instruction at 0x00007FFAF45C5747 referenced memory at 0x000000007FFF3FF0

This happens when Explorer likely called an instruction in its code that attempted to reference memory that is corrupted, not present, or unreadable. You can attempt using SFC, DISM, or try applications like the Windows-native Windows Memory Diagnostic tool. You'll have to be patient while trying, though. Also, make sure your RAM is not faulty or mismatched. Otherwise, if none of the options above worked, look for clues. If you get error codes such as 0x00000050 (PAGE_FAULT_IN_NONPAGED_AREA), try checking your drivers, especially disk drivers, for updates or corruption. I hope this helps. Let me know if this helps!
