I think the saves folder might of cleared or something else happened. 

1.18 is not supported yet.

Could be malware or something interfering with the laucher(read it in MC-101571) 

Cave generation was updated in 1.17.1 so this might normal.

Can you give the people trying to help you a screenshot with the debug menu?(F3)

Duplicate of MC-139741. 

in 1.17.1. Its probably the shadows affecting the screen. The vignette cause by the shadows disappearing, IDK why that happens. 

 I think that its either that the game is programmed to sheer Bee nests manually or a error in the code. Hope my bad thought/explanation helps in a way.

This isn't a bug related to the MC java edition launcher , but more or so of a  web issue. Could be that something happened to original site.

Its MC-100949. Basically delayed shield blocking

Should be on the [[Bedrock Bug Codebase|https://bugs.mojang.com/projects/MCPE/issues/MCPE-114688?filter=allopenissueshttp://example.com]. Could be that the computer or the game somehow unloaded the buttons. I honestly don't know.

Same story as the person who files MCL-18214(where the launcher won't load because of a bug) maybe its a bug in the system causing this. I don't know honestly. 

works in 1.17.1. Could be that the A.I. is somewhat dumb or flawed in a way because it will not find an alternative rout when presented with a barrier blocking the target. Hope this explanation helps. Also hope that Mojang improves the A.I. so that this is patched

Bug with the computer or maybe the controls in MC?

this is similar MC-118107.  Its probably because E opens and Closes the inventory, so maybe cus of that holding it down will cause the inventory to flicker as its rapidly opening and closing. 

Happens in 1.17.1. Maybe its because the player mounts the Minecart/Boat too fast causing the player to kinda noclip. Sorry if this might not help, Im new here.

Could be a stuck key, try to fix it in the controls section of the settings.

Your comment is not relevant to what I said. I have no idea why you would consider flying up as "fall damage" maybe listen to the bedrock community instead of marking everyone's as "resolved" when you haven't helped or done anything

Thanks for the answer.

Sorry to bother you.

Hi Galaxy_2Alex,

The problem persist on the latest version 1.16.1

At the end I attached the log in text format.
