There are sadly some bugs with the new launcher which stop gamers from enjoying. Therefor I needed to create this publish to offer steps to obtain and use the old launcher. Nethertheless, you'll be able to report bugs regarding the old and new launcher on the bug tracker (if they aren't already reported) to make sure the devs are aware of them.
The previous launcher might be downloaded on https://minecraft.net/en-us/download/various. If the outdated Minecraft.exe launcher will not be working for you, you can download the "Linux / Different" variant. Using this directly to launch the sport will show a message that it's best to update the launcher. You possibly can stop that by launching the launcher.jar file it downloads to the Minecraft knowledge (%appdata%) folder when you first launch it straight. GAMING
The new launcher should have created a file known as launcher_profiles.json.backup in your Minecraft information (%appdata%) folder. Just rename it to launcher_profiles.json and substitute the prevailing file. You would possibly have to login afterwards while you start the launcher.
