Like Ehylo said, the error is not strictly limited to auto-updating to the latest build.
You will recieve this error if you use 1.16.5 Forge regardless of what you do. You may also recieve it on unofficial launchers or custom modloaders.

Can you explain more? Try following this: https://cdn.discordapp.com/attachments/813715704191778817/813716666839728148/CMD.gif

@redac1d You need to upgrade the version from the server. If it does not work, then reinstall completely TLauncher. Remove the checkbox with Force Update.

Uninstall OptiFine

@quidd60x They are located in .minecraft/libraries/me/deftware/EMC-F-V2/latest-(mc version)/

@fastasfack OptiFine issue. You either need to disable the shaders or remove optifine entirely

When you set your fall distance to 8, that means that you must fall at least 8 blocks before it will trigger the bucket. I would probably lower it to however much it takes to damage yourself.

Unfortunately there is not, if you are referring to the plugin that spreads random ore everywhere.
Xray texture packs, baritone, xray, esp, and anything else cannot bypass this.

If you mean paper antixray (where there's hardly any ores anywhere) you can use legitmode to bypass this, and baritone will also mine these blocks normally.

@woodcutter Usually not. You could try editing settings where applicable, but it probably will not help much if there is heavier anticheat (If you get lagged back from flight, speed, etc)

@dyiing Thanks.

You have to type out the entire line you want to remove, and then it will be removed. Some lines cannot be removed though.

If you hold the shift key while on that error screen, it will show you where the "me" folder is located.
Normally it is in the AppData folder. To get here, press win + r, then paste in %appdata%\.minecraft\libraries

@sportzpikachu If your still interested if you saved the old instance your waypoints and stuff are still there, to fix your error follow this https://discuss.aristois.net/topic/23/invalid_checksum-error and launch the old instance and you should be fine, sorry about the inconvenience.

@captainoebis I figured it out, i was running it in the wrong directory
