The object has a bluish tint, possibly another planet?

There's nothing in the way of venus, what you've imaged is simply venus partially illuminated during one of its non-full phases.

 

The sun is illuminating it from the right of your image. Same phenomenon as a partially full moon.

Venus is in a crescent phase right now.  The only thing blocking light is the rest of Venus.  It is exactly like a crescent Moon.  The blue-ish tint is chromatic aberration.

Nothing, or Venus itself - take your choice.

Being inside our orbit we generally only see Venus from a side and not all of what we see is illumimnated, the unilluminated bit appearing dark blocked/covered.

 

Moon is similar except for a day it sits outside us and inline with the sun so we see a fully illuninated disk. Even a day after a full moon you will notice that one side is no longer round.

 

The time Venus would be full is when it is on the opposite sune of the sun and that means Us - Sun - Venus so it is daylight, and the sun is in the path so not a good thing to try find.

Mercury, Venus, Mars, Jupiter, and Saturn all have phases, although the phase of the gas giants will always be very close to 100%, or a full disc.

 

JPL's HORIZONS can tell you the phase for any of these planets. Pick your time span and select option 10 for the table settings. You'll see that Venus is at about 19% now and that Mars and the Moon have similar crescent shapes now, but not for long.

Being in focus would help a lot, too - make the situation far clearer....
