The game crashes atleast 50% of the time or more when trying to join a local world. When the game crashes, the whole client goes down with a red screen and boots to desktop. Entirely closing Minecraft. This makes it impossible to run the game file on a server of any kind. The world file has had all of the addons stripped off so its completely vanilla with no addons. And even loaded up older saves of the same world to experience the exact same thing. Once the world loads up, it plays fine with no signs of corruption. Everything worked perfectly until updating to 1.20. I have only played in the world for a few minutes after getting it to load successfully. Unsure if it crashes if you play longer. Ill AFK with the world on for a bit and report back my findings.
