I was testing some effects given to the player when they are on ice. When I climbed a ladder with these effects, it shot me into the air.

I have these effects running on a loop:

/execute at @p if block ~ ~-1 ~ ice run effect give @p minecraft:wither 1 50

/execute at @p if block ~ ~-1 ~ ice run effect give @p minecraft:jump_boost 1 200

/execute at @p if block ~ ~-1 ~ ice run effect give @p minecraft:slowness 1 4

/execute at @p if block ~ ~-1 ~ ice run effect give @p minecraft:poison 2 50

/execute at @p if block ~ ~-1 ~ ice run effect give @p minecraft:hunger 1 255

When you climb a ladder that touches the ground, you get shot into the air and will die because of fall damage
