VanillaFix Compatibility failed about mixincompat

[NotStirred]

As a quick fix you could try using the thin version of vanilla fix found here, it doesn't include mixin and might work for you.
I will look into this issue at some point when I am less busy

Thank you for your willingness to help me. Unfortunately, the version you gave will still cause the client to fail to start
Here is a bug report
debug.log
latest.log

I'm very sorry that the original VanillaFix this problem that should have been solved by their author and wasted your time.
I have tried many times to post requests and feedback to their developers, but they are no longer maintaining the original VanillaFix. I have not received any response to my request, but because it is too important, I have been unable to abandon it (because I operate the server , The dynamic texture function without the original repair will cause a large number of low-profile players to be unable to play).

I am not in a hurry to solve this problem, please wait for you to have time before you consider helping me,
Thank you very much and wish you a happy life
