1.17 homescreen instead of 1.18

It's modded, you probably put a mod that changes the background into 1.17. There is no proof of any resource packs installed or being used, so this is invalid.

And please update to JAVA_17 to run the game normally.

v2i0, I wanted to say that OptiFine is installed, not other mods.

OptiFine is also a mod, so we're unable to accept this report. Feel free to report it to the developers of OptiFine, however. 🙂
