Iris doesnt want to load any shader
idk why, but it outputs an error into the chat :
net.minecraft.server.ChainedJsonException: Invalid shaders/core/basic.json: Non [a-z0-9/._-] character in path of location: minecraft:basic_tessControl.tcs

try updating Iris to 1.8.8
Modrinth
Iris 1.8.8 for NeoForge 1.21.1 - Iris Shaders
Download Iris Shaders 1.8.8+1.21.1-neoforge on Modrinth. Supports 1.21.1 Neoforge. Published on Feb 20, 2025. 160258 downloads.
same problem
i just switched to 1.8.7 to see if the problem remains, i used 1.8.8 in the beginning
try without other mods maybe?
but wich ones?
i have over 180 mods in there
all of them
except for sodium and iris ofc
it will take days
to load the game with only sodium and iris?
it takes only a couple minutes to set up and launch a new instance with only those two mods installed
it works fine with only sodium and iris
Solution
i found the mod that stops the shader from loading
this one: https://modrinth.com/mod/cat-armor
can you maybe put an incompability info onto the modrinth webside or github page so other people also know about it?
