MCL-17339Minecraft Launcher Hangs Fresh Linux Install
When I run the Minecraft Launcher on Pop_OS 20.10 (based on Ubuntu 20.10), it has an error and hangs permanently. The error is:
[Error: 2021-03-17 02:06:06.918652895: SettingsManager.cpp(106)] : Deserializing: * Line 1, Column 1
{{ Syntax error: value, object or array expected.}}[Error: 2021-03-17 02:06:06.918669075: SettingsManager.cpp(106)] : Deserializing: Expected object
[Error: 2021-03-17 02:06:06.918679145: SettingsManager.cpp(111)] Failed parsing main configuration file: .../.minecraft/launcher_settings.json
I have tried killing all minecraft processes and relaunching, deleting my .minecraft folder and reinstalling/relaunching, installing from the official .deb file, and installing from the Pop Shop software manager.
Launcher log, bootstrap log, and launcher_settings.json are attached. I have not edited anything, this is happening with a default installation from multiple sources.

If you use this `launcher_settings.json`, does it help?
{ "channel" : "testing", "customChannels" : [ "testing" ], "formatVersion" : 0, "locale" : "en-US" }

@peterix bump. Any word on this?

I was able to replicate this bug on Ubuntu 20.10 today. I downloaded the .deb file from minecraft.net and installed it with `sudo dpkg -i Minecraft.deb`. When I ran `minecraft-launcher` in the terminal, it updated itself and got stuck with exactly the same error message about parsing the launcher_settings.json file. That file is the same as the one attached.
Also, try these:
- put the minecraft-launcher executable from this into ~/.minecraft/launcher/
- install this – it puts the same version of the bootstrap into /usr/bin/
minecraft-launcher-928.tar.gz
minecraft-launcher-928.deb
@Petr Mrázek Thank you for these suggestions and alternate launchers. I've tried everything you suggested, and I am still having a problem, but the root cause now seems to be different. See below for what I tried.
All on Ubuntu 20.10
1. I downloaded a fresh Minecraft.deb from minecraft.net. I created the ~/.minecraft folder and added the launcher_settings.json above to it, and ran the launcher. It updated as usual, then failed to launch. One interesting line in the output said "Current executable is not in game directory, update and run game directory version"
2. I put the launcher from the gzip file above into ~/.minecraft/launcher in place of the one that was already there. I then ran `minecraft-launcher` on the command line. It failed in the same way as in step 1.
3. I Renamed the ~/.minecraft folder to allow the new launcher to create its own. I uninstalled the existing minecraft-launcher, including manually deleting /usr/bin/minecraft-launcher. I ran the launcher and it updated as usual, then failed with the original error about parsing launcher_settings.json.
4. I then copied the launcher_settings.json with "testing" into ~/.minecraft and ran the launcher again. It ran its update again, closed the updater window, and hung again. This time, the error messages are different.
The attached files are the launcher and bootstrap output corresponding to each step above.
Seems related to issue 17227
@peterix @[Mojang] Petr Mrázek The official launcher will still not run on Ubuntu or Pop_OS.
For anyone with this problem, I'm switching to GDLauncher
We haven't been able to replicate this in VMs.
What GPU(s) do you have? What GPU driver(s) do you use with it?
I have a Radeon RX 590 Series made by Sapphire.
Below is the output of `sudo lshw -c video`. It just says "amdgpu" for the driver.

OK... I don't have this specific card around, but let's follow this trail and try with some GPU options.
It should look sort of like this afterwards:
{ "channel" : "beta", "customChannels" : [], "deviceId" : 12345, "formatVersion" : 0, "locale" : "en-US", "productLibraryDir" : "/home/peterix/.minecraft/products" }Does it behave any better?
