A mod is patching code that does not exist here
Applies to Forge, NeoForge, Fabric, Quilt.
What it looks like in your log
Critical injection failure: @Inject annotation on onRender could not find any targets matching
What causes it
A mod tried to inject into game code that is not present in this Minecraft version, which almost always means the mod build does not match the server version.
How to fix it
The trace names the mod behind the failed injection. Install the build of it made for this exact Minecraft and loader version, or remove it.
