Additional Context

No response

This might be unrelated, but do you have the flywheel-iris-compat mod? It’s mostly for performance but might be worth a try.

Everytime I use flywheel iris compat, my game crashes, presumably being incompatible with my iris version.

iris flywheel compat has been updated to latest iris.

then provide the crash report

Ah, well despite this, my game still does crash.

your iris flywheel compat is NOT up to date. you need https://modrinth.com/mod/iris-flw-compat/version/iris-1.20.1-0.2.5

Ah, my bad. This issue also seemingly solved itself randomly, even without flywheel compat. So I'm not sure what happened.
