Playing fabric (api: 0.36.0, loader 0.11.6), minecraft 1.17, immersive portals 0.10. Have a chunk of other mods, including BetterEnd and BetterNether. As well as Better Strongholds (yung). I also am running lithium and krypton.
Game instantly crashes when placing the last eye of ender in the end portal (right after the heavy crash/thrum). Nether Portals function as expected.

I think I have the same issue. I removed Lithium but still got the same error. Got BetterEnd and IP with some other mods as well.

Does Lithium on server side makes any diference?

latest.log

BetterEnd solved the issues. But now it looks like the render distance is something like 2 but in a sphere shape when in The End.

First don't use lithium with IP because it may memory leak.
It seem to crash inside better end sky rendering

GL11.glEnable(GL11.GL_ALPHA_TEST);

GL11.glEnable(GL11.GL_BLEND);

Does this issue happen without this mod?

@AzureMonument Does the issue happen with better end and without Immersive Portals?

Just tried it, and it looks like it doesn't.

Just tested it, no- if I remove better end it works fine. Should I go move this crash over to better end?

I have encountered a similar issue but was not creating any crash log and I found that after removing better end the crash no longer occurred
my full mod list is:

(here better end is disabled)
