Minecraft Not responding page keeps on popping up after the 1.20 and 1.21 update

The not responding page popped up whenever I'm more than around 5 minutes into the game and if I die. After that, i would press wait and it would go back to normal but after 7 secs, it would appear again and no matter how many times i pressed it, it kept popping up. It stopped just recently but im just reporting this bug in the hopes that it won't come back to me again.
