There are sadly some bugs with the new launcher which forestall gamers from taking part in. Therefor I wanted to create this post to offer steps to download and use the old launcher. Nethertheless, you can report bugs regarding the old and new launcher on the bug tracker (if they aren't already reported) to ensure the devs are conscious of them.
The outdated launcher could be downloaded on https://minecraft.internet/en-us/obtain/alternative. If the previous Minecraft.exe launcher is just not working for you, you may obtain the "Linux / Different" variant. Utilizing this directly to launch the sport will present a message that you must replace the launcher. You possibly can stop that by launching the launcher.jar file it downloads to the Minecraft information (%appdata%) folder when you first launch it immediately.
The brand new launcher should have created a file called launcher_profiles.json.backup in your Minecraft information (%appdata%) folder. Just rename it to launcher_profiles.json and change the present file. proximal's blog might have to login afterwards once you start the launcher.
