If more info is requested I will be happy to send some. Im going to delete my inv. to see if that helps. Thanks!
Did this create a crash report (.minecraft/crash-reports/crash-<DATE>-client.txt)? If so, can you please attach the file here?

Yes, will attach right now. From further inspection the chunk seems to have glitched❓ in NBT explorer I have singled out the chunk file, it is 9,9 if that helps at all, and the program crashes on expansion of the file.

More information: Upon loading world in MCEdit, MCEdit crashes... Something is wrong with chunk 9,9, and there is no way that I know of to delete it. Something seems to be crashing due to NBT data, and the only things were the command blocks in that area. I am pasting the commands which I have saved below
/execute as @a[limit=1,nbt={slot:-106b,id:"minecraft:crossbow",Count:1b,tag:{display:{Name:"{\"text\":\"Portal Gun\",\"color\":\"dark_aqua\",\"bold\":\"true\",\"italic\":\"false\"}"},Enchantments:[{lvl:5,id:"minecraft:quick_charge"}],Damage:0},Unbreakable:1b}] run say hi

I have some logs at my report:
mc-144971

I think this duplicates MC-148147, the only thing that seems to change is the class name in the first line of the report, which can happen between versions
Is this still an issue in 1.14 Pre-Release 5?

Please check if that's still an issue for you in Minecraft 1.14.3 Pre-Release 2.

It is no longer an issue in 1.14.3 Pre-Release 2. World is working fine.
