i cant place or break blocks or anything else

I dont know what caused the bug but i am unable to break or Place block, doors beds etc. i am still able to interact with blocks that are already placed such as beds, chests, crafting tables you get the Point. i have tried reloading the game, but as i dont know what caused the issue i dont know how to solve it.

i notised one other person had a similar problem and he solved it by checking his keybinds and saw that he didnt have one for attacking/destroying, i checked and i have the keybindon, i also tried changing it and it still didnt work.

i was playing alone in survival mode, i died underwater by drowning and when i respawned i Went into creative mode to fly back and retreave my stuff, after picking them up i got into my boat and Went back into survival mode after getting back to shore i notised i couldnt break or Place blocks.
