There was no crash.
Ah. Uh, sorry. I was just corrected on MCForum as well. That value is inputted as a string. Hadn't looked at it that way.
Confirming I have this issue.
This also happens to me. When I first start up the game it runs fine. If I leave a world and enter a world (whether the one I had just left or a new one) this bug happens. I have to exit Minecraft and then load the game back up from the launcher to clear the bug.
Also, it continues playing the music from the game's home screen over top of the music the game world plays.
Can't add attachments, but here's a screenshot. http://i.imgur.com/UgDlE1w.png
I have this issue as of 1.19.41. This is a seriously old bug.
Desktop, tablet mode disabled (of course), AMD drivers, everything up to date.
