      The bug

      Originally I had a data pack but I narrowed down to 3 commands with 2 being ran every tick.

      First command:

      scoreboard objectives add Health dummy

      Repeating command block:

      execute as @e[type=minecraft:wither_skeleton,sort=nearest] store result score @s Health run data get entity @s Health 1

      Chain command block attached to the repeating one:

      execute as @e[type=minecraft:wither_skeleton,sort=nearest] store result entity @s Health float 1 run scoreboard players get @s Health

      The Wither Skeleton stops being able to get to the survival mode player when those 2 commands are active.
      This didn't effect Zombies.
      I didn't try other mobs.

      I asked people to confirm that this is not only happening on my Windows 10 PC.
      And it appears to be a bug in the code instead of my installation.

      How to reproduce

      1. Enter the following command into a powered, repeating command block: 
        data merge entity @e[type=wither_skeleton,limit=1,sort=nearest] {Test:0}
      2. Spawn a wither skeleton: 
        /summon wither_skeleton
      3. Switch to survival mode: 
        /gamemode survival

        → The wither skeleton has trouble pathfinding to you
