nbt data limit thing

i joined the server walked around and saw somebody dropping chests (i still have my stuff in inv) walked to the chests wondering if they have something in them (nbt data) i picked some up ( like 5 or 6 chests) and got kicked for exceeding reading limit and now i cant join the server anymore because it keeps kicking me for the reason that theres too much nbt data and im asking if its possible to clear my inventory while offline so the stuff is gone and i can join the server again because i really like the server and theres a screenshot as proof



it would be nice if it would be able to get fixed
and i cant wait to join the server again
