Thanks for submitting. The crash had nothing to do with FPS Reducer but with Better Recipe Books I believe. It should now be fixed in the 1.1.2 version for Minecraft 1.19.2.

Huh, strange. If it was incompatibilities with FPS Reducer, I could understand it, especially considering that Not Enough Crashes said:

But Better Recipe Books... That's really odd for me.
I'm glad it's fixed :)
