(there was no "attach file" prompt under Crash Report file and latest.log)

Immersive Portals is using Iris internals, so it broke with Iris 1.5. You'll need to update Immersive Portals for it to work with Iris.

Looking again, it looks like the updated version of Immersive Portals might only be available for 1.19.3, so you might need to update your Minecraft version as well.
