Unable to modify Player Data

So, maybe this will be marked as WAI, but I couldn’t find a feature request or bug report on this topic. I mean, worst that can happen is nothing.

If you try to modify the Data of a Player the game just says „Unable to modify Player Data“.

To reproduce this, you just need to use a command like /data or execute store and will get the message.

Hopefully this will be „fixed“ soon!
