Here is another crash from this version. It is also due to one piglin that is just spawned in the world and my game crashes with the similar report. It can also be taken into account to analyze this problem.

Hi! Sorry for the late reply. I have run the latest snapshot version 25w21a and the pre-release 1-1.21.6. The game is much more stable and it seems no crashes happening right now no matter how much bat i put in the world. Thanks for fixing that.

I have tested the memory and there was no errors in my pc. Anything else i can do to fix the issue?

Here I have some new discovery with this problem. I tried the same way in different patches of minecraft, from 1.20.1-1.21.5, and the same rendering issue only happens on patch 1.20.4+, which is the patch that the bat’s texture is reworked. So I think this problem probably comes from the rework model or something related to this. I’m not sure if this is a useful information or not. Hopefully this new information could be taken into account and solve this annoying problem.

After this memory test, I recreated a new instance and new world for verification. The same issue was still happening with entity ‘bat’ rendering error. This time the crash report says like this:

java.lang.IllegalStateException: stream has already been operated upon or closed

The same question is still occuring with the entity ‘bat’ rendering issue when the bat is trying to hang on a block(because when I saw a bat hang on a block and my game crashed like before) and the error from java is still from the reference pipeline with some implementation error here. Anything else I can do for further testing and solving the problem?

Hi! I have done the windows memory test and there is no issues in my memory. Is there anything else I can do to have a test or verify in order to solve this problem?

It seems that the crash comes from the bat’s transformation while the bat is trying to stand on a block and remaining stable. During this transformaion, the game is having a larger chance of crashing. I just spawned many bats using the spawn egg and my game crashed because of one standing bat. I am not sure if it is a useful information but hopefully it is useful. Please someone sees this issue and I really want a good game experience rather than continous crashing.

The same issue is still existing in my game right now. Any update for this issue please?

I don’t know the exact trigger for the game crash, but I can describe what I did in every world before the game crashing. Just simply fly for a while in spectator mode then switch to creative mode, and the game suddenly crashed with an entity ‘bat’ being ticking. The problem is always due to a bat and i tried in the nether/end, it seems not to crash anymore(I didn’t test for so long but the crash all happened in the overworld). After checking the crash log, the errors are always in the same format like I mentioned in the bug description related to ‘stream’. This is really consistent to reproduce even though I create a new world, switch to a new instance, or even a new launcher, the same crash still happens.
