The game itself does not freeze, only the screen display. I have tested that with narrator and my other friends on the world. The rest of the programs running on my computer, like discord or task manager, are completely fine. The only way to correct this is to terminate the Minecraft game entirely and reopen it through the launcher however after about five to ten minutes of being in the game, it will freeze again. This server exists in the version 21w14a but this option is not in the available choices list for the issue report.
