[MC-268855] Typing /function then space closes the internal server

When updating a world to this snapshot and typing /function followed by a space the internal server closes. This does not seem to happen in worlds with a small amount of functions, only worlds that have datapacks with many many functions. This does not happen in 1.20.4

Steps to reproduce

Load a world with a large amount of datapack functions
Type /function followed by a space

Expected Outcome

Function namespace previews appear
Takes me back to single player worlds instead of server list

Could you please attach a minimal setup datapack to reproduce this? Please also attach the full launcher log found in [minecraft/launcher_log.txt|https://minecrafthopper.net/help/finding-minecraft-data-folder/].

Attached launcher_log.txt and here is a datapack. Was too large to upload so you can get it here

I can confirm this with the attached datapack. This behaviour does not occur in 1.20.4

Removing this pack from my world caused it to become corrupt. I'd advise people wanting to test this to use a new world.
