Minecraft wiki entry for Things_not_to_do, associated text: A player who wants to play with any other items that cause explosions when used, should not do so near the world spawn point. If the player dies after blowing up the world's spawn point and loses the spawn point from a bed or respawn anchor, the player instead spawns at a now-cratered area. This makes it hard for the player to get out, lacking any tools or blocks. To help avoid this, the player may want to mark the world spawn point when starting a new world.
