Snapshot 22w18a Crash

What I expected to happen was...:
For it to load like it normally does.

What actually happened was...:
It took longer to load than usual and I got an error that brought me back to the Minecraft Launcher.

Steps to Reproduce:
1. Go to the Minecraft Launcher and hit play. (Minecraft Demo only, to my knowledge)
2. Wait for experimental world to load.
3. Once at 100%, it sends you back to the launcher and gives a crash report.

I'm positive this is only for the demo snapshot version, since I don't have Minecraft, but it's still strange nonetheless. I tested out the 1.18.2 demo and that worked fine.

Unfortunately, I haven't managed to reproduce this issue. I have tried loading into an already-created Demo World and generating a new one - neither seem to cause a crash.

i am also having same issue for few days i think it might be caused by antivirus software we use i think so 

other people are able to make new world in buyed launcher 22w18a and also in demo launcher 22w18a version, my friend who was having same issue in demo launcher is also facing same issue after buying Minecraft 

may i know what is your pc environment if you don't mind asking you because i use bundled java

Thanks!

22w19a crash report: https://bugs.mojang.com/secure/attachment/484529/crash-2022-05-15_00.14.14-server.txt

guys i think removing 22w18a snapshot from you computer may allow 22w19a to work because some days ago after 22w19a came i tried downloading 22w18a snapshot the downloading was successfully but i was not able to open world in 22w18a as well as 22w19a 

 

from 22w18a was launched i was having this issue but when i downloaded it i faced same issue for both latest snapshot i started facing this issue for snapshot 22w19a after installing snapshot 22w18a

 

so first i try reinstalling my launcher but it didn't work 

hence i removed snapshot 22w18a and than reinstalled my launcher and that work for me 

We believe this issue is fixed in 1.19 Pre-release 1. If you still experience this in that version, it might be caused by a third-party launcher. If you still get this crash in 1.19-pre1 or later, please attach the following:

  • A new crash report

  • Any changed settings for the version (for instance, any non-default JVM options)

  • Which launcher you are using (including the version number)

  • If you are using the official Minecraft Launcher, also attach launcher_log.txt
