Here are the Mods I was using:

And a Screenie of the Issues:

Here's the latest.log :

latest.log

EDIT: My "Inventoryprofilesnext' folder is empty. I double checked it with the normal 1.16.2 inventory profiles (which does not have this issue), and that is also empty.
Also, unrelated, it doesn't sort enchanted books or nonstackables. I don't know if this is a feature or an issue related with this bug.

Hi,
I can't reproduce either of you problems.

the mod was unable to load the embedded configuration file:

[11:11:02] [Render thread/INFO]: [STDERR]: java.io.FileNotFoundException: inventoryprofilesnext:config/rules.txt
[11:11:02] [Render thread/INFO]: [STDERR]: at net.minecraft.class_3304.method_14486(class_3304.java:65)

and a texture

[11:11:36] [Render thread/WARN]: Failed to load texture: inventoryprofilesnext:textures/gui/gui_buttons.png
java.io.FileNotFoundException: inventoryprofilesnext:textures/gui/gui_buttons.png

But more interesting is that minecraft it self can't load it's own file

[11:11:03] [Worker-Main-5/ERROR]: Couldn't load truetype font minecraft:negative_spaces.ttf
java.io.FileNotFoundException: minecraft:font/negative_spaces.ttf

So I guess there is something more going on. As a last resort I can suggest is reinstalling the game and deleting %USERPROFILE%.minecraft folder NOTE This will delete all of your saved world so don't do it if you care about them

p.s.
How sorting works depends on the embedded configuration file so I guess if it's not loaded sorting won't work properly

Odd. I wonder why that's happening. So there's nothing else to be done besides reinstalling the game? I don't mind doing so, I'll just archive my worlds elsewhere on my laptop. Thanks for the help.

Please update here if it works

Did not work. Deleted all the minecraft files and Reinstalled. Problem still occurs. Here's the log again

Hi

I was able to reproduce your problem, As a temporary solution please add this mod https://modrinth.com/mod/modmenu too.
You probably want it any ways since it adds a button to access all mods configurations in the main/pause menu

Thank you! Will try!
