so the new update for the launcher broke minecraft being able to even launch, its stuck around taking up 8.5 MB of memory i know for a fact when something is stuck/ not responding, and then i open task manager and see that the amount of memory its using does not change its like stuck on the number, i go to curseforge to see what minecraft is doing and i see this

i dont have good memory but i know for a fact that it never did that before and i am pretty sure its the reason why minecraft launcher is not working, it will never take more than 1 minute to load. and i put a image of the task on task manager am not sure if it looks bad because i can see it for some reason, but its stuck on 8.5 MB because its stuck on a number of how much memory its using means its not working/ cant find something and takes a nap it will sometimes use more or less memory but that does not matter because its broken anyways,
i asked a ai on what it means and it said
đź§© What Each Line Means
EventBus.doCastFilter
Forge is trying to deliver an event to a mod listener. This method filters listeners based on type—if the event doesn’t match the expected type, it can throw aClassCastException
.EventBus.lambda$addListener$11
This is the listener that was added to the event bus. It’s a lambda (anonymous function) that’s supposed to handle the event.EventBus.post
Forge is broadcasting the event to all registered listeners. It tries twice—once at line 302, once at 283—likely for different phases or priorities.FMLModContainer.acceptEvent
The mod container is accepting the event and passing it to the mod’s listener.ModContainer.buildTransitionHandler
Forge is transitioning the mod through its lifecycle (e.g., setup, load, etc.) and running the event asynchronously.CompletableFuture$AsyncRun.run
The event is being handled in a background thread usingCompletableFuture.runAsync()
.ForkJoinPool
lines
This is Java’s thread pool executing the async task. It’s standard forCompletableFuture
unless a custom executor is used.
⚠️ What Might Be Going Wrong
Mod mismatch: A mod might be listening for an event type it wasn’t meant to handle, causing a
ClassCastException
or silent failure.Java version conflict: Forge 1.18.2 was built for Java 17. Running it on Java 21+ can break classloader assumptions or async behavior.
Missing or broken mod: If a mod’s listener is registered but its class isn’t loaded properly, the event bus can’t deliver the event.
i even launch it without using curseforge to launch it and it is still stuck
so it has to be the new minecraft launcher update and i hope it is not because of a new UI, did you guys just make the update and call it a day and not test if the launcher still works after the update, i am unable to change to a older java/ minecraft launcher because i dont know how to do that and i am pretty sure the minecraft launcher will update to the newest update, am not sure if the update changed the java version and if that is true that means it would not even matter if i changed to a older java because it will update to the newest java anyways there is nothing i can do, and why is it not loading why is it not working is anyone playing on my version of the minecraft launcher that i have why is it doing this the onlything i can think of why it does not work is because of eventbus completablefuture forkjointask forkjoinworker forkjoin pool because i am really sure that it did not do that before, what is going on i launch minecraft launcher from minecraft installer because that has the account that owns minecraft it does not work i launch minecraft launcher from curseforge it does not work the only thing i am sure why it broke is because of the new minecraft launcher update, if i need a better pc for minecraft launcher to work i am not buying better pc parts for minecraft launcher to work because i am not gonna pay like 1000$ just to run one game one game why is it me that has the problems with updates/ crashes that can break my save/ game, someone can pay for me to get a better pc because i am not spending 1000 $ just to have less problems
the thing is to play more games you have to spend money to have better pc you spend 1000 $ to play a 30 dollar game you pay 1000 $ to get better pc parts but you have to then have to pay money to get the 30$ game, if i need a better pc for minecraft launcher to work i can buy better pc parts but that will cost a lot of money or report a minecraft launcher bug and make sure you put points into luck because minecraft is a poplar game and there would be a lot of people reporting bugs and stuff and you need luck for the devs or someone to do something about it because they might not even see your bug report it could turn into days to weeks into months before they see it and they try to fix your problem but it could turn into days to weeks to months before they fix it and there could be new problems that will be a road block for you and repeat you wait and wait and wait before it works with out problems, if the devs will even have the sanity to fix all the problems that you will have/ have. And then a update will break the game for you and the devs might just dont do anything about it because they dont want to fix your problems no more. i do not like launcher updates because it can break the launcher and the problems might never get fixed, and they can take up space on my pc and then when i run out of space because of launcher updates the launcher might never work because you do not have the latest update. ok i think i am done talking about the launcher bug and what i think might be causing the launcher to not work and complaining about having to buy better pc parts. 50 minutes of waiting for the launcher to see if it taking a ton of time to work and i think 50 minutes is good for saying that the launcher does not work/ is broken.
