Edit: Somehow forgot I was gonna mention that I am using version 2.0.0 of the mod on game version 1.16.5 and Fabric version 0.16.10.

I don't think I have any mods which conflict with this one, but I still removed Shoulder Surfing just incase. However, this crash log blames Camera Overhaul, and the game runs when I remove it.
Here is a manually-written list of my mods (as opposed to the one buried in the crash log), with ones I've tried removing marked (I also tried an unrelated few which I had added between when the game ran and when it stopped working, before I realized the log blames Camera Overhaul):

• AppleSkin

• Borderless Mining (Tried)

• Camera Overhaul (Tried, source of the problem)

• Chat Heads

• Chat Sounds (Tried)

• Cloth Config API

• Cool Rain (Tried)

• Enhanced Block Entities

• Entity Culling

• Fabric API

• Falling Leaves

• FerriteCore

• First Person Model (Tried)

• Forge Config API Port

• Iris Shaders

• Lamb Dynamic Lights (Tried)

• Memory Leak Fix

• Mod Menu

• Not Enough Animations

• Presence Footsteps (Tried)

• Reese's Sodium Options

• Roughly Enough Items

• Sodium

• Sodium Extra

• Crash Pipe (Tried, but strangely enough, it made the crashing game look different, so I removed it just to be safe and I'm still having the problem)

Crash log file included:

crash-2025-02-18_04.12.09-client.txt

Plus the top part of the crash log, which makes me think Camera Overhaul is doing it.

2025-02-18-7.log.gz

It may be that I used JDK 21.0.2 to compile the mod. Try switching to Java 21.

I just tried installing the latest version of the JDK and nothing changed, so I checked for updates with Java itself and it said I already had the latest version. So, when that didn't work, I simply tried re-downloading and running the installer, and it didn't work either.

I also tried another solution I thought of, which was to go into "Java and memory" under my installation's settings in the Modrinth app, and switch "Java installation" from "Default Java 8 installation" to "Custom Java installation." It didn't seem to do anything either.

If it helps, however, I did a little testing.

• The game seems to run fine on my current installation if I switch from "2.0.0-fabric+mc.1.15.0-1.16.5" back to the next latest listed version in Modrinth, "1.4.1-fabric-universal."
• Running the latest version on a fresh (still 1.16) installation with only 3 mods (This one, Cloth and Mod Menu) doesn't work either.
• This problem does not occur when using this same new installation to test the mod on versions 1.19.2 or 1.21.2, but does still occur on version 1.17 flat (the very next version after 1.16.5). I have not tested any more versions beyond this.

I tested running CameraOverhaul-v2.0.3-fabric+mc[1.16.0-1.16.5] on fabric for 1.16.5, ensuring that I'm running it using JDK 17, and it ran just fine. Please update and check again on your end, I don't think I've changed anything, but I'm now certain that I used JDK 17 to compile the thing.

Ah, I see my fault, it's supposed to be Java 8 up until 1.17, and Java 16 until 1.18..
