Crashing and bug

I tried crafting netherite armor but it wouldn’t let me craft it. I reset mincraft many times and it still wouldn’t let me create it. Later on I went to sleep in Minecraft, it then started crashing. I reset Minecraft again. I loaded in my world and the screen was stuck on the sleeping screen. It would then later crash. No matter how many times I tried, it would always crash. Please help with these bugs. Thank you
