Control delays of (W,S,D,A) after closing inventory

When I open the inventory using the E key and then close it, I experience noticeable input delay for about 2–3 seconds. Movement keys (W, A, S, D) feel delayed or unresponsive. After that period, controls return to normal. This happens every time I open/close inventory, and occurs in every world (new or old). Reducing render distance and graphics settings does not solve the issue.
