I recently started playing on a survival server, and had no issues crafting until I opened the recipe book to check a recipe. After that, the recipe book would be automatically open whenever I opened my inventory or the crafting table GUI (even if I made sure to close it), and sometimes the recipe book GUI would be overlapping the inventory or crafting table GUI in a way it clearly wasn't supposed to. Also, the game would crash if I tried crafting anything with the recipe book GUI closed.

Crash Report:
The game crashed whilst rendering screen
Error: java.lang.NullPointerException: Rendering screen
