same but for fabric 1.19.2

Also getting this. It happens every time if you try to open anything that has an inventory while REI is still loading. I have to make sure I don't try to look at my character's inventory, my storage system, crate, pouch, etc, for at least 10 seconds after loading a game. This has been happening since Stoneblock 3 came out, so wasn't introduced by any recent changes. I just never thought to report it until now.

I'll attach my crash report, but the relevant lines in the stack trace are:

java.util.ConcurrentModificationException: null
	at java.util.ArrayList$Itr.checkForComodification(Unknown Source) ~[?:?] {}
	at java.util.ArrayList$Itr.next(Unknown Source) ~[?:?] {}
	at me.shedaniel.rei.impl.client.registry.screen.ScreenRegistryImpl.getFocusedStack(ScreenRegistryImpl.java:144) ~[RoughlyEnoughItems-8.3.583.jar%23230!/:?] {re:classloading,pl:rei_plugin_compatibilities:B,pl:runtimedistcleaner:A}

I don't know what the OP's gist is, but it doesn't appear to be a crash report, and seems to cut off too early.

Hmm, can't attach .txt or .zip files?

Edit to add that when this happens, there is a warning dialog from REI stating that it is still loading, so it seems that REI knows it isn't ready yet, but still something fatal happens.

Turning off Caching Entry Rendering can solve this problem temporarily.

@BuddhaBuddy1 can you create a separate issue for yours? would be great!

Sure, created [Bug] REI Crash opening any Inventory while REI is still initializing

@papillo12 Your issue is a different issue from @TexBlock, and I have created another issue #1299 to track it instead

@TexBlock Your logs does not include a crash, do you have a crash report instead?
