I'm getting a crash on load occasionally. It doesn't seem to happen every time I load, but intermittently. Below is the crash report:

I'm not sure why you think this particular crash is caused by IE, but it looks like RenderType#create is not actually thread-safe on 1.16.5. I'm not convinced that IE ever calls it off-thread, but we call it during static init, which doesn't really have threading guarantees.

Are you saying that this could be related to the Create mod? If not, do you have any idea of what mod is causing it?
