Shaders Suddenly started to crash clients at server

I'm running my server about 2 months now and all the players were able to join and use shaders normally. Suddenly some players had their client crashing when enabling any shader. Didn't found anything at the server that caused any error and they can still join without enabling shader. It's weirds since only the client crashes and that everything was fine before that, can anyone help me with that?

We need a log file of one of the crashes to figure out what’s going on.

So to reproduce this crash you have to have ad astra, iris and customizable player models installed and attempt to wear a space suit. This combination somehow causes iris' batched entity rendering to attempt to call startGroup on the hand twice, causing a crash. This means removing any of the 3 mods should temporarily resolve the issue while @IMS can investigate it

took a look, CustomPlayerModels is hijacking Iris and causing unintended behavior the error isn't in Iris or Ad Astra

Had som testing here and it seems that if the player is using the Netherite Backtank from create they crash. We'll do some testing with CPM but the netherite Backtank is probably one of the problems
