The bug
Minecraft crashes when launching snapshot versions 17w49a/b and 17w50a. I have already seen MC-121738 , which says that disabling custom resolution would fix the problem. This didn't work for me, however.
To clarify, all versions and snapshots prior to 17w49a work perfectly fine, even 17w48a works perfectly.

Sorry for the late response. No, unfortunately, it doesn't. When launching I made sure that I had no resource packs on. Do you know of any another solution that might help? Thanks
I have a similar problem, but my game can't launch 1.13 again. Additionally, unlike some of the duplicates, the problem was started when I opened the resource pack menu, without actually loading any resource pack. [I put this here in case it helps in fixing the issue at all. If a mod wants me to take this comment down, I will.]
Hello all,
I have managed to find a fix for this (that has worked for me at least):
Simply go to your .../AppData/Roaming folder, and rename your .minecraft folder to something else. Then, open minecraft client, login, and download 1.13. This should create a brand new .minecraft folder. Once that's done, move your saves file from the original .minecraft folder into the new one that is created. Now, you should no longer get the error, and you have all your saves! (you may remove the old .minecraft folder if you wish)
tl;dr: Get a fresh install of Minecraft through removing the .minecraft folder and letting the mc client create a new .minecraft folder.
Thanks, Pie
