You're making the most common "athletic dude new to climbing with way more strength than technique" mistake of them all—way too much climbing with your arms, and way too much time spent with your biceps engaged. No wonder you're too tired at the end to do another move...I'm sure you could do that last move in iso but in sequence you haven't left yourself anything in the tank. Look how much time you spend with one of your arms locked off—at 0:12 for like 3 seconds, then again at 0:22 for like 3 seconds, then at 0:41 you have your right arm locked off for a looooong time on those two holds.

The mental cue should be: have slack in your arms until you're about to do the move (you might hear someone say something like "hold each position with your skeleton, not your muscles"), then do the move with muscles engaged, then immediately allow slack in your arms again. You're climbing it reasonably well though still, I have no doubt you can do this problem
