I think it is an incompatibility with another mod but I am not sure, the only one I can think of that is the cause is Quark but I don't know.

Can confirm this issue too

With just pictures i can't fix anything.
What modloader? Mod list? MAVAPI Version? Minecraft version?

Anyways, if it's forge, most likely is an incompatibility due to sinytra connector + Forgified Fabric API.

I use Forge, yep, but this issue didn't happen before but after I installed another mods I think, it can be Quark but I'm not sure

I am using connector and it is 1.20.1 forge version, there are no variants of axolotl, on the version im using, unless im searching for them wrong

Sinytra Connector not supported. Also 1.20.1 support has been dropped.

If you say so but it has issues without connector too

So sad that still don't support 1.20.1
