A new update has been released to address a few issues with the 1.21.80 release. Please continue to report and upvote any bugs you find at bugs.mojang.com.

Fixes:

Graphical

• Fixed an issue where Vibrant Visuals (Experimental) would sometimes apply to worlds that do not correctly support it
• Fixed an issue that could cause pixelated distortion on specific iOS devices (MCPE-218490)

Gameplay

• Fixed a bug where hitting blocks while swimming would cause players to slow down too much (MCPE-201832)

Performance and Stability

• Fixed a crash that could occur when loading a world with leashed entities in it
• Fixed a crash that could occur after activating "SplashPotChange" and "LingeringPotChange" resource packs (MCPE-217599)

API

• Fixed bug where block custom component event beforeOnPlayerPlace was not using read only privilege. Due to V1.X.X of scripting releasing without read only privilege, the fix is now only applied to V2.X.X and higher versions of scripting

Components

• "minecraft:leashable" component values can once again be updated at runtime via component groups
• "minecraft:leashable" presets are now re-evaluated every tick instead of only when the entity is leashed
