Fix SetLastError

in uv

Solution

The "SetLastError" error in uv typically arises when a function fails but its error code isn't properly propagated to the caller, leading to inaccurate error reporting. To fix this, ensure that every function call that can set an error also checks its return value and uses `SetLastError` with the appropriate error code before returning failure to propagate the error up the call stack effectively. Also, when consuming Windows APIs immediately check GetLastError and handle the error.
