I have completed all of the TOTS events and also opened all the packs and have definitely exceeded 40 packs but still last reward in TOTS event is locked

According to the first image (7419) you haven't exchanged sufficiently many tag combinations for player items in the "Triple Formula".
Collect some more tags if needed, claim player items through the triple formula, and once you have exceeded the 40 reward claims, you can collect your 117 UTOTS player.
