I have had the same exact problem making my own texture pack. While stumbling over another texture pack I have realized my mistake. To change the broken and bugged textures go into your "pack.mcmeta" and change the pack format from 4 to 5 fixing the broken skins
Hello, I have been assisting Trey via Remote Desktop. Here are a list of things that we have tried as well.
☼ Reinstalling multiple times after deleting the .minecraft directory.
☼ I sent him an exact copy of my minecraft folder and that didn't work either. It still says "Guest".
☼ Have ran Malwarebytes and CCleaner to clean up his drive + Registry. (Found many issues... none had any impact on minecraft)
☼ Found older versions of Java installed. I removed them. Trey now has only the latest 32-bit and 64-bit java installed.
I'm seeing similar errors in the launcher_log.txt. Most of the snapshots are getting this error.
