Executing at all entities to kill all enitities makes the game crash

THIS WILL ONLY WORK WITH "Upcoming Creator Features" turned on.

I threw 2 items on the ground right next to each other with the name "anyname' then I executed this command by mistake

/execute at @e[type=item,name=anyname] run /kill @e[r=5,name=anyname]

and it made the game crash. I'm not sure if it works on the previous version of the /execute command(EDIT: it does not work with the old /execute. Just the new one)... This needs to be fixed ASAP because I do not want people doing this on my realm.

This command gives the same result.
/execute at @e run /kill @e
