I'm assuming it's due to the new 1.21.7 port, but I thought I'd inform you of this if you weren't already aware. This mod no longer works with Iris, and it completely prevents the game from starting when both are installed. Hopefully this is helpful! I can attempt to show you a crash report if you need it, but I assume you'll be able to recreate anything I would send as long as both mods are in your mod folder.

    i have the same issue, there was also a crash on a server when i used CPM without iris, but i don't know how to replicate the crash. the startup crash when Iris + CPM are installed together does occur for me, though.

    When either Iris or CPM is removed, the game launches successfully. I believe this is an issue on CPM's side due to the other issue I had on a server.

    Here are a few warnings caused by CPM when the game is loaded without Iris:

    • [ForkJoinPool-1-worker-4/WARN]: Mod cpm uses the version 0.6.22a which isn't compatible with Loader's extended semantic version format (Could not parse version number component '22a'!), SemVer is recommended for reliably evaluating dependencies and prioritizing newer version

    • [main/WARN]: Reference map 'CustomPlayerModels-Fabric-1.21.6-refmap.json' for cpm.mixins.compat.json could not be read. If this is a development environment you can ignore this message

    • [Render thread/WARN]: Removed resource pack cpm from options because it is no longer compatible

    CPM itself seems to mostly work fine without Iris installed, though. Not sure if the warnings above are relevant.
