SOLVED - Collision detection - TURTLE

[OuateDePhoque]

Hello y'all!

I'm new here, so I hope my question will be clear enough!

I'm trying to create a Breakout game using Python n Turtle.
I created my lists of blocks and my main block to .clone() but
wenn the ball reaches the top of the game, where the blocks are, it only erases the first block...

I tried to solve this issue with different kind of loops, but the proble is still present...

I hope someone can help me!
THX in advence!

CODE:

# CREATING BLOCKS

block1 = turtle.Turtle()
block1.shape("square")
block1.speed(0)
block1.shapesize(2, 4) # Size of block 40x80

# BLOCKS ROW Nr.1 (10 Blocks)
blocks_row1 = [block1.clone(), block1.clone(), block1.clone(), block1.clone(), block1.clone(), block1.clone(),
block1.clone(), block1.clone(), block1.clone(), block1.clone()]
# BLOCKS ROW Nr.2 (10 Blocks)
blocks_row2 = [block1.clone(), block1.clone(), block1.clone(), block1.clone(), block1.clone(), block1.clone(),
block1.clone(), block1.clone(), block1.clone(), block1.clone()]
# BLOCKS ROW Nr.3 (10 Blocks)
blocks_row3 = [block1.clone(), block1.clone(), block1.clone(), block1.clone(), block1.clone(), block1.clone(),
block1.clone(), block1.clone(), block1.clone(), block1.clone()]

all_blocks = [blocks_row1, blocks_row2, blocks_row3]

def starting_block_positions():
for i in range(len(blocks_row1)):
blocks_row1[i].penup()
blocks_row2[i].penup()
blocks_row3[i].penup()

blocks_row1[i].color(random.choice(colors)) # ROW Nr1
blocks_row1[i].goto((-400 + (82 * i)), 460)
blocks_row2[i].color(random.choice(colors)) # ROW Nr2
blocks_row2[i].goto((-400 + (82 * i)), 418)
blocks_row3[i].color(random.choice(colors)) # ROW Nr2
blocks_row3[i].goto((-400 + (82 * i)), 376)

# COLLISION WITH BLOCKS
elif ball.ycor() > 356: # COLLISION WITH BLOCKS
while counter_collision < len(blocks_row1):
if (abs(ball.xcor()) - abs(blocks_row3[counter_collision].xcor()) < 20) and (abs(ball.ycor()) - abs(blocks_row3[counter_collision].ycor()) < 40):
blocks_row3[counter_collision].hideturtle()
ball.setheading(270)
ball.forward(BALL_SPEED_STANDARD)
break
elif (abs(ball.xcor()) - abs(blocks_row2[counter_collision].xcor()) < 80) and (abs(ball.ycor()) - abs(blocks_row2[counter_collision].ycor()) < 40):
blocks_row2[counter_collision].hideturtle()
ball.setheading(270)
ball.forward(BALL_SPEED_STANDARD)
break
elif (abs(ball.xcor()) - abs(blocks_row1[counter_collision].xcor()) < 80) and (abs(ball.ycor()) -
abs(blocks_row1[counter_collision].ycor()) < 40):
blocks_row1[counter_collision].hideturtle()
ball.setheading(270)
ball.forward(BALL_SPEED_STANDARD)
break
counter_collision += 1
