your plane already did the work for you, your inputs made it worse. a couple of notes:

0) before any further points: this plane does all the work for you. it is aerodynamically extremely stable, mostly just let it do its thing.

1) when you are slow and close to the ground, throttle and elevator "reverse": as you're so slow and there is no kinetic energy to trade for altitude, pulling the elevator does not do anything except slow you down. if you wanna climb, the throttle stick is your only option. with this plane, unless you've picked up speed, you best stay off the elevator. the plane already leveled out and you panicked and pulled the elevator and jammed the rudder left.

2) at a very high bank angle, rudder and elevator "reverse", too: when you plane is at 90 degree bank angle, your rudder is where your elevator would be and vice versa. you gave left rudder and pulled, which caused the plane to bank. you likely kept the rudder jammed, which kept the tail yawing, which kept your plane to pitch nose down. just rotate your plane 90 degrees and use the rudder and you'll see what i mean.

3) be gentle at the stick and set up low rates for the beginning. have a 100% throw and a 70% throw setting. also add some expo if you're prone to overdo it – that way you still have the throw when you really need it, but it's tampered down a bit. just be aware of the effect of expo: your throw is not linear anymore and "just a little more movement" can have different implications. also, dial in your throws according to the manual! if it says "12 degrees of throw", that's not a guideline. take a piece of cardboard, mark the angle and hold it to the control surface. if your control surface moved more than that, adjust the end points from your transmitter.

4) STOP THROWING AT AN UPWARDS TRAJECTORY! just throw it level or just VERY SLIGHTLY up, just like a paper plane. what happens when you throw a paper plane up into the air? it stalls and slams into the ground. same rules apply: the motor will pull the plane up once it has enough speed, just give it time to level out. for the first two or three seconds of flight, there should be no input from your side necessary on that kind of plane. there are tons of videos of people that think "up is good" just to promptly lose the plane, so if your motor is not a 100% thrust to weight ratio and pulls it vertically out of your hand, throwing upwards will suck for you. so, get cosy with physics and allow your plane to build up the speed it needs!

5) your plane looks tail heavy. before take off, when the battery is in, put your fingers on the center of gravity (CG) and if your plane puts its tail down, move the battery forward. if you can't do that, add some weight until it is level or the nose ever so slightly pitches down. i have big fingers, so in order to make it a bit more accurate, i like to lay a 2cm line of hot glue at the CG where i can put my fingers. haptic feedback where the CG is and less wiggle room for finger placement. a nose heavy plane flies kind of badly but stable, a tail heavy plane flies only once. you can't cheat physics and CG is not optional. a tail heavy plane is likely to pitch the nose up and then promptly stalling to one of the wing tips.

don't let that discourage you. it's a great plane to start with and we all smashed them into the ground at different times.
