1.Place 2 commands blocks and active them during the same tick:
/summon ArmorStand ~ ~1 ~
/tp @e[type=ArmorStand,c=1,r=5] @p

It works perfectly, the entity is summoned and teleported to the nearest player.
2.Kill the ArmorStand.

3.Now, add the tag NoGravity to the entity when you summon it.
/summon ArmorStand ~ ~1 ~

/tp @e[type=ArmorStand,c=1,r=5] @p

The entity is summoned but not teleported.
When you disconect/reconect the game, the entity is teleported to you.
