1. I'm having the same problem griffithpilled, still unsure how to fix it but if I find a way I'll let you know! I think a problem could be that we're trying to run it on 1.19.3 and optifine doesn't yet have a full-proof download, the only 1.19.3 optifine downloads that exist currently are still previews and not entirely done. - In other words, not a lot can be done at the moment. This is what I'm assuming anyway, but as I said if I find a fix I'll come back with an update.
2. ChampionAsh5357, no offense but that is not the most helpful comment in the world. Especially if someone posts lookin for a fix, not a replacement.
