I'm experiencing a similar issue, game crashes on launch in 17W49b

No crash report is created. Launcher Log says:

20:12:13 launcher Preparing to launch minecraft client for 17w49b
20:12:14 launcher Checking installations.
20:12:14 launcher Minecraft client 17w49b is ready to start.
20:12:14 launcher Starting!
20:12:14 launcher Using default game log configuration client-1.12.xml (outputs XML)

the problem also persists with the snapshot 17w50b

I cant seem to find why this is happening on my own can you please tell me a fix for it

try and make a new directory, it works for me!

Petrydog - could you elaborate more on what you mean by "try and make a new directory"? Because I'm confused as to which directory you are referring to - there are hundreds of them.

what do you mean?

Forward-resolved to MC-123460 because that is a more general report with more details about this issue.

Still an issue in 18w01a.
