Good day,

I am using JER in my modpack which I am slowly updating from 1.16 to 1.18 and the newest update (0.14.0.154) of JER for 1.18 gives me the error message screenshotted below when trying to start my game. Returning to the previous update (0.13.2.153) allows minecraft to boot as normal.

Could you please provide a client log?

latest.log
I was watching the log as it went though and it noted a missing JEI, but JEI is fully updated as far as I can see.

Update: I just double-checked JEI in the curseforge app and seems like it hadn't done the usual appears-at-the-top-of-the-list thing to notify for an update; I've done so and all is well now

So we can close this?

Yes
