This very likely isn’t a bug, you need to keep the area lit up enough, otherwise crops will break automatically when a block next to them is updated.

This isn’t a bug, it just doesn’t rain in Savanna biomes.

This is still the case in Minecraft 1.20.1. They also keep growling and jumping to the position even after the armor stand is broken. Only a relog seems to fix the latter, while the growling remains until you walk far enough from the position where the armor stand was. Really weird.

The latest Nvidia drivers in which they made "performance improvements for Minecraft" have issues (e.g. Minecraft versions 1.12 and below have graphical errors) and can cause crashes, e.g. with some rendering mods like Sodium. Try downgrading to any driver version below 526.47 and see if it works normally again. If yes, Mojang can't really do much about that I think, Nvidia needs to fix that.
