as soon as i press the key for freecam my game crashes. The mods i have are :appleskin, Armourchroma, boat item view, bookshelf,boosted brightness, continuity, controlling, enchant descriptions, entity culling, fabric api, iceberg, item scroller, legendary tooltips, malilib, mod menu, mouse tweaks, status effect timer, zoomify and finally tweakeroo.

If anyone can help me with this issue that would be greatly appreiciated

no-log-no-help. In other words please pastebin the crash log (or the .minecraft/logs/latest.log file) , otherwise nobody can have any idea what might be wrong.

I have the same issue. Here is pastebin of crashlog: https://pastebin.com/Xw1V2gpd
It works when I go into tweakeroo config and toggle it on, but crashed when I activate it by binding a hot key.

@Fruggu That crash would suggest you are probably using malilib for 1.19 while you are in 1.19.1.

(Unfortunately the crash log does not include the full mod file names, which for my mods would show the MC version it was built for.)

Sheesh, that was it. I didn't even think to check the version of my mods. I just updated them earlier today and I must have missed that one. Thanks! I will go away in shame now :(
