CAUSE

This issue occurs because the Lsass.exe process does not initialize a 64-bit pointer variable and then transfers data to this variable from a 32-bit pointer variable by using Windows on Win32 (WOW). Therefore, the 64-bit pointer variable becomes invalid, and the Lsass.exe process crashes when the variable is used to access memory.
