A rare mixin error

[TeQTabanca]

Basic questions:

• [X] I am actually using ketting, and not any other software (e.g. magma)
• [X] I am using the latest Ketting version at the time of writing for the Minecraft version, that I am using
• [X] I have provided full server logs and not a crash-report
• [ ] I have checked all items without reading.
• [ ] I have provided proper reproduction steps
• [ ] I have ticked all boxes

What Minecraft Version is your Server on?

1.20.1

Full Ketting Version

1.20.1-47.3.6-0.3.25

Description of behavior

I set up the ForcePack plugin. I opened the 2nd client to test but it did not allow the player to enter the server. Because I did not enter the hash value of the source package. The plugin had already given a warning, but there were also mixin errors in the console. I tried again but it didn't give the mixin error. I don't know what's causing the problem.

Reproduction Steps

Steps to reproduce the behavior:
1. Install the ForcePack plugin and change the resource pack hash.
2. Run the server
3. See the mixin error

Note:The last time it happened was when I was setting up this plugin. So this may not be caused by the plugin.

This is not a mixin error, and seeing that its a file system exception leads me to believe that:

1. you already have a server running
2. your virus scanner is trying to scan the world files before the server can have access to them, leading to those errors

Then it is caused by AdvancedBackups mod. Because sometimes it tries to backup worlds.

No, this error was caused by authme while trying to save player data
