Can you remove the _build and .elixir_ls folders at the root of the project and let it rebuild again?

It means that the lsp isn’t even starting, I don’t know if the esl-erlang package provides the erlang in the same way as the ubuntu package, did you updated the erlang package too or only the elixir?
By the way, did you use the repo or asdf to update?

I removed previously installed packages and installed them again, this time following elixir docs.

If you do want to go with docker at some point, this seems like a good article about docker+elixir https://dwarfte.ch/posts/phoenix_dev_environment_with_docker_compose/

Perhaps check out the troubleshooting tips at GitHub - elixir-lsp/vscode-elixir-ls: Elixir language support and debugger for VS Code, powered by ElixirLS. · GitHub (the image you posted looks like vscode?). What do you get if you type elixir at the same prompt you launch vscode from?
If you don’t find anything, perhaps add a post here with some more info about exactly how you’re opening a project in vscode (eg. is it from the command line at the root of a mix project?), and maybe scan the elixir-ls log output & include anything that seems relevant.

Ok, I solved problem by switching from Ubuntu to OpenSUSE Leap 15.3. I don’t know what exactly caused this error, but default elixir (1.11.3) and erlang packages from repository seem to work just fine.
Thanks for all replies, I appreciate that. At this moment I will not learn docker and just go with WSL2.

I have one more question. I’m trying to setup postgres on WSL. I installed postgresql and postgresql-server, but I can’t start the service.
Can I somehow enable postgres service without systemd?

I assume you were trying to start it with systemctl, which won’t work without systemd. Not sure what OpenSUSE comes with, but most distros have service to run System V init scripts [edit - system can also start systemd units, which most packages designed, like postgres, to be run as services will install these days]. Try which service to see if you have it, then if it’s there, man service to read up on how to use it.
If things are set up right, sudo service postgresql start should get you started. I admit I haven’t gone to the trouble of automating starting services in my wsl - as my system keeps running for weeks on end it’s no trouble to just run this on reboot. But it can be done if needed.

What I have done is create a batch file in Windows, with the following contents:
wsl --user myusername --distribution Ubuntu --exec sudo service postgresql start
Then created a task in the “Task Scheduler” in Windows that starts when I log on to Windows. This ensures that when WSL is used, the postgres service is already started. As can be seen above this is for Ubuntu, but if you can manually start your service in your distribution in the console, this can be automated in the same manner as above.
Here the prerequisites for the above to work:
sudo visudo
Add the following to the end of the file:
%sudo ALL=(ALL) NOPASSWD: /usr/sbin/service postgresql *
I have documented my installation steps for Elixir/Erlang in Ubuntu on WSL here, in case you are interested:
