Please help me!

Minecraft seems to crash every time I launch into a world.

Here is the crash log below.

[Client thread/WARN]: Ambiguity between arguments [teleport, destination] and [teleport, targets] with inputs: [Player, 0123, @e, dd12be42-52a9-4a91-a8a1-11c01849e498]
[20:55:07] [Client thread/WARN]: Ambiguity between arguments [teleport, location] and [teleport, destination] with inputs: [0.1 -0.5 .9, 0 0 0]

I am not sure what this log means but it is crashing my game every time i attempt to join a world.

Any help would be great, thanks!
