Vault Hunters not responding when I pause

[TLPD]

The game would be not responding whenever I pause or when the vault result screen popup. When I reopen the world, my player would be in the wrong location from when I crashed.

The last thing in that log is it saying it is saving chunks for the vault dimension, there is no error message.

Saving chunks is normal when you pause the game to go into a GUI,

but if you say the game is not responding and it is not saving the player's position then there is likely something broken in this process.

You should check you have the latest version then contact the mod/mod pack author.

 

To see what it is actually doing when it is not responding we would need to see a "thread dump".

https://www.baeldung.com/java-thread-dump

so we can see where it is stuck.

There's nothing in the thread dump when it is not responding, the terminal also not goes back to prompt mode after using jstack

This is thread dump before I press Escape key

[warjort]

The thread dump before it stops responding isn't going to tell us anything.

 

If jstack can't get a thread dump, that suggests there is something more serious wrong with the java virtual machine.

e.g. something has corrupted native memory or some other bug/problem in the jvm, graphics card driver or operating system

I have no idea where to start debugging that problem, other than suggesting to check your drivers are up-to-date.

 

It's not something that will be Forge's fault, it has no native code.

It could be one of your mods, some of them include native libraries.

 

Whoever provides your java implementation would be the best people to ask why you can't get a thread dump.

You could also try reinstalling java or a different java implementation to see if that fixes the problem.

It might be something with Windows 11, I tried running the same modpack in Linux and it works without the problem.
