1. Add an account
2. Select the Steve or Alex skin in the Upload Skin interface
3. Add an instance with game versions 22w45a+
4. Start the instance and you will find that the skin may be different

I guess it has something to do with Mojang adding new default skins in 22w45a.

The test results are shown below: #2784 (comment)

Using Local Skin File and LittleSkin does not seem to be affected. Blessing Skin is not tested.

HMCL hasn't fully support to change you skin on offline accounts in these Minercraft versions.

I tested it with 1.19.3 and it is indeed Alex skinned!

Probably only the beta version has this problem

[burningtnt]

Is this issue caused by the comparator of Game Version?
Could you test with the PR Collection version, as it contains PR #2700

@burningtnt I’ll do it right away.

My wording was inappropriate and too one-sided before. I apologize for this.
I added 3 offline accounts with different usernames and tested using 22w45a and 1.20.4.

In the picture, the one on the left is the game version, the one in the middle is the username, and the one on the right is the skin type.

Thank you so much! I will check the codes and try to fix this.

The prediction from the UUID to a default skin hasn't support such Minecraft version. Therefore, when HMCL thought the UUID would provides Steve and doesn't launch a authlib-injector service, The skin calculated by Minecraft comes to another skin.

We will fix this bug later. As this is not a big problem, so it would not be traced in #2925.
