I can confirm this. The following exception occurs when trying to reel in the fishing hook, which then stays underwater without moving.

Also, this command fails with an unknown error.

/loot spawn -3.33 64.00 -152.18 fish minecraft:gameplay/fishing -4 63 -153

However, this one works.

/loot spawn -3.33 64.00 -152.18 loot minecraft:gameplay/fishing

The issue still exists with the current .msi installer as of 2018-04-27. It isn't relevant to the Java launcher.

This issue is still present.

@CubeTheThird, then what did? There was no pre-existing desktop shortcut.

It seems that the .msi installer does not set the working directory of the desktop shortcut correctly; on Windows 10, viewing its properties gives a blank 'Start In' field.
Changing this to the Minecraft installation directory solves the problem.
Also, I uninstalled and reinstalled the launcher, and the same thing happened.

Keep in mind that there's no such thing as 1/3 of a durability point. Unbreaking makes it so that there's a chance that you won't lose a durability point.
