Please Help With This weird Glitch

Alright so i was summoning the wither right, and it killed me but my inventory glitched... no my player as a whole glitched.When i respawn my screen was shaking (but not like side to side or up and down) in a way your mouse cannot shake. Then my tinkers construct stuff glitched and my longsword, lumberaxe, and my cleaver turned into this weird rainbow tiles and my tinkers pick turned into a wooden pick. As i tried to get into my inventory, when i press E it instantly closes the inventory gui, but for that quick millisecond i went into my inventory i see that my player is pink/red. Other small thing i have noticed is that i cant pick up items and exp, i cannot kill the wither after i respawn (or else it crashes my game),and lastly even though this stuff was SUPPOSED to go in a gravestone it stayed in my inventory and i left i gravestone where i died.

Thank You for reading
P.S. That Wither is still on the Loose
