Game freezing while interacting with inventory or lootbox

Can't really describe what causes it but randomly if i try dropping some items from my inventory or i try to loot a deathbox (mostly armor swaps) the game will freeze for a sec or two when i pick up/drop the first item and then go fine till i'm done looting, can happen even multiple times in a single match and that's really annoying since this are core mechanics of the game expecially during fights (armor swaps).

This is what should happen everytime https://www.twitch.tv/videos/2360676745?t=00h43m57s and the proof i can fast swap.

This are multiple clips of the actual problem

I assume the inventory and the box bug where it makes the game freeze are related since the same thing happens.
