There are sadly some bugs with the new launcher which forestall players from enjoying. Therefor I wanted to create this submit to provide steps to obtain and use the previous launcher. Nethertheless, https://arkadne-igre.net/ can report bugs concerning the outdated and new launcher on the bug tracker (if they don't seem to be already reported) to verify the devs are aware of them.
The old launcher will be downloaded on https://minecraft.internet/en-us/obtain/different. If the previous Minecraft.exe launcher is just not working for you, you'll be able to obtain the "Linux / Different" variant. Utilizing this directly to launch the game will present a message that you must update the launcher. You can forestall that by launching the launcher.jar file it downloads to the Minecraft knowledge (%appdata%) folder while you first launch it instantly.
The new launcher should have created a file called launcher_profiles.json.backup in your Minecraft knowledge (%appdata%) folder. Just rename it to launcher_profiles.json and replace the existing file. You may have to login afterwards while you start the launcher.
