Every times i open any inventory with mouse tweak installed it just crash.
yes that is a modpack.
i do not know which mod cause that crash but i am certain it is not mousetweaks because mousetweaks work just fine on its own with just forge and jei.

i will eventually found which mod is causing this, just letting you know there is a crash.

Mouse tweak version: 2.10
Crash report : https://pastebin.com/DGYSbGen

I'm really not sure what this is caused by, my guess is some other mod bundled what it shouldn't have.

probably the case, the only mod i know that does it is Wireless crafting thermal but i don't have that mod installed and it doesn't crash when i use it with mouse tweaks.

Closing as this is likely not a mouse tweaks issue.
