Вот сам код, чтобы я не делал персонаж не прыгает, в чем проблема?

Основная проблема то что у Вас позиция отрисовки героя всегда на 800 (player_x, 800).

Несколько предложений по оптимизации и упорядочиванию кода (по желанию):

  • Отрисовку лучше выполнять только единожды в конце цикла.
  • Клавиши считывать не всегда а только по событию.
  • вместо таких услови if player_animation_count == 3 можете использовать число деления по модулю player_animation_index = player_animation_count % 2 будет 0 или 1 (а player_animation_count % 3 будет 0, 1 или 2) и т.п.
  • Старайтесь не использовать повторы в коде, это упростит его редактирование.

это:

walk_left = [
    pygame.image.load('images/player_left/player_left1.png'),
    pygame.image.load('images/player_left/player_left2.png'),
    pygame.image.load('images/player_left/player_left3.png'),
    pygame.image.load('images/player_left/player_left4.png'),
    pygame.image.load('images/player_left/player_left5.png'),
    pygame.image.load('images/player_left/player_left6.png'),
    pygame.image.load('images/player_left/player_left7.png'),
    pygame.image.load('images/player_left/player_left8.png'),
]

можно записать так:

walk_left = [ pygame.image.load(f'images/player_left/player_left{x}.png')
    for x in range(1, 9)]

Код:

keys = pygame.key.get_pressed() # инициация клавиш
while running:
    clock.tick(144)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()
        # считываем клавиши только по событиям разгружая процесс
        if event.type == pygame.KEYDOWN or event.type == pygame.KEYUP:
            keys = pygame.key.get_pressed()
    
    if keys[pygame.K_a] and player_x > 50:
        player_x -= player_speed
    elif keys[pygame.K_d] and player_x < 550:
        player_x += player_speed
    if keys[pygame.K_w]:
        is_jump = True

    if is_jump is True:
        if jump_count >= -10:
            if jump_count < 0:
                player_y += (jump_count ** 2) // 2
            else:
                player_y -= (jump_count ** 2) // 2
            jump_count -= 1
        else:
            is_jump = False
            jump_count = 10

    if player_animation_count == 3:
        player_animation_count = 0
    else:
        player_animation_count += 1

    bg_x -= 2
    if bg_x == -1920:
        bg_x = 0

    screen.blit(background, (bg_x, 0))
    screen.blit(background, (bg_x + 1920, 0))
    screen.blit(figure[player_animation_count], (player_x, player_y))            
    pygame.display.update()
