Keyboard Delay/Bug

Before the Nether Update was Made, the keyboard was fine but ever since both 1.16.0, 1.16.1 and 1.16.10 was made, the W, A, S, D, the Space Bar and the Shift Button makes a buffer. when I press the keys i've mentioned, it moves late like about 1 or 2 seconds and when I release the keys, the movement contiues for a while. The W key is mostly affected and lasts up to 2-3 seconds (now starting to be up to 5-7 Seconds) after releasing the W Key but the A, S, D, the Space Bar, and the Shift Button is less affected and lasts about the same as the W key. Also, (rare times) when the movement finally stops, the game breaks or places a block randomly.
