/kick in repeating command block crashes the realm

Having a player kicked trough a Repeating Command block with /kick causes the realm to crash for an unknown reason.

This bug only happens on a realm and I couldn't reproduce in a single player world.

Might be useful to know, the realm had Beta API & Upcoming Creator Features enabled.

Steps to Reproduce:
1. Join a Realm with a Friend or more
2. Place a Repeating command block with 0 ticks delay containing the command: /kick friendName
3. Then power the command block with redstone power or set the command block to always active.

Observed Results:
The friend that had his name inside the command block will get kicked, however the Realm crashed completely shortly after it happens. (I believe the command somehow manages to execute a second or more times on the already kicked player)

Expected Results:
The friend that has his name in the command block should be kicked without the realm crashing.
