Issue description

I have recently been having a problem with MCreator and wondered what was happening.

What happens is when I create a new mob and go to import a new texture from my computer, the whole program ends up crashing.

Error log: https://drive.google.com/file/d/1uVHcEH-r4JSndA-S_1jOC5TVpeMpvhQP/view


  • CPU - AMD FX-8350
  • RAM - 16 GB
  • GPU - GTX 970
  • OS - Windows 10 Home (64 bit), version 1709


There will be an official fix for this bug in MCreator 1.7.8. Workarounds can be found in the comments of this issue.

Issue comments

Try to open file user/preferences.conf inside MCreator's installation directory and add new line ui=legacy

Try to import the texture after you do this and it should fix the bug. Please report back if this worked so we can provide an official fix. Thanks!

More details about this bug which is actually a Java bug: https://bugs.openjdk.java.net/browse/JDK-8178873

I can confirm this can be fixed using legacy UI. This is a known Java bug. One can reproduce this in many ways, one of them is by creating a "God Mode" shortcut on the desktop. Create a folder called DevLinks.{ED7BA470-8E54-465E-825C-99712043E01C} on the Desktop and it will cause MCreator and any other Java app with Windows UI to crash.

We have found a fix for this and it will be fixed in 1.7.8 and most likely backported to older versions in the future. For now, one can fix this by setting the ui to legacy mode as instructed in the previous comment.

Thanks for getting back,

I changed the UI to legacy and it now works, thanks for providing all of the details. I do actually have a god mode folder on my desktop with a similar name (GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}). Was this folder the reason?

Thanks again!

i had the same problem , did everything you said and still not working .
