I previously used the "Visuality" mod for a long period of time without any problems. All my mods are constantly updated in their latest and most recent versions. So I decided to update most of my mods to 1.21.5. Now, when I try to open my world, this new version crashes. Minecraft runs, but the world can't be opened.
Note: The crash report includes the word "muerciélago" in Spanish, which is "bat" in English. I use Minecraft in Spanish (Mexico).
note2: My cat was causing trouble earlier so I killed it, but the supposed bug moved on to a random bat in a nearby cave, I guess...

Visuality still only supports 1.21.4 at this time, likely you're trying to run it on 1.21.5 which is not yet supported. I've had a similar crash which results in similar issues you are having. Either downgrade your Minecraft and mods to 1.21.4 or wait till an update is available for 1.21.5.

0.7.10+1.21.5 should work, https://modrinth.com/mod/visuality/version/0.7.10+1.21.5

0.7.10+1.21.5 should work, https://modrinth.com/mod/visuality/version/0.7.10+1.21.5
