Iris shaders will not load at all.

I have tried multiple shaders, updated, reinstalled both shaders, fabric, and Iris but I still get the same issue. This is the code I get from the error. net.minecraft.class2973: Invalid shaders/core/basic.json: Non [a-z0-9/.-] character in path of location: minecraft:basic_tessControl.tcs I need help : (

Solution:

After much trial and error I have discovered that this issue is due to a mod (specifically the Caligo mod). So, if anyone else gets an error like this, I would double check the mods you have installed.
