[1.21.11 - VulkanMod 0.5.10] Game Crash on Start with VanillaTweaks Resource Packs

[The-Letter-M]

Describe the bug

Minecraft crashes on start up when any Vanilla Tweaks resource pack is loaded and already enabled, specifically when Remove Reloading Screens is enabled. Without RRS, the game starts and instead freezes upon attempting to load the resource packs. Attempting to reload Resource Packs from this point with F3 + T leads to a similar crash. After the crash, all resource packs are disabled and must be re-enabled.

Minecraft is able to run when the pack is disabled before launch and then re-enabled after launch. Other Resource Packs (such as Bare Bones or Redstone Tweaks) seem to function perfectly fine.

Tested on Hyprland Arch Linux, Nvidia RTX 3060.

Steps to reproduce

1. Have any Vanilla Tweaks Resource Pack loaded and enabled.
2. Enable VulkanMod.
3. Attempt to launch the game.
4. Game will either crash on startup (if Remove Reloading Screens is enabled) or fail to load resource packs.

it seems to be an issue with vanilla tweaks' pixel consistency features, or different texture resolutions as a whole according to some peoples errors. i removed the pixel consistency features and it launched for me

Hm, I disabled every module in the Fixes and Consistency section on Vanilla Tweaks and I still cannot launch the game with the resource pack already enabled. I can't seem to figure out which other modules are causing the crashing, but it's more than just the consistency fixes causing the issue.

@The-Letter-M Can you send the vanilla tweaks resource pack you are using?

@JJ10-GNU Of course, sorry for the late reply.

@The-Letter-M This issue should be fixed on the latest vulkanmod version. Sorry for the late reply. My bad.

@Versatile-Z1 Just tested it.
It does seem mostly fixed! It still crashed initially, but the game won't crash so long as you don't use any modules that affect the main menu.
