Description of the issue:

When launching, Minecraft freezes on a white screen and will not progress or crash. This only happens around half of the time my game launches.

Crashlog:

Here is the debug.log, https://pastebin.com/6iZAJT1h and here is the latest.log, https://pastebin.com/QzhqhY5d
As you can see, the dev log stops at KubeJS, and that is when it freezes. In the debug log, it stops just past the Immersive Engineering loading of Pollution of the Realms. If this is on their end, please let me know.

Versions & Modlist

Forge 39.0.10 and IE 7.1.0-145.

Try removing KubeJS and/or Pollution and see if that helps? ^^
