Formatter hangs on VSCode 1.42.0

I get this everytime I try to save an Elixir file:

Running Save Participants for 'test/users/notifications/mailer/some_mailer_test.exs': Formatting

It doesn’t even save the file until i Cancel the message above. Once I cancelled it, it also formats the file. However, it’s a really annoying behaviour.

It works fine if you downgrade VSCode to 1.41 or less.

Am I the only one with this problem on VSCode 1.42.0 ?

I’ve seen there are other Extensions with this problem, here’s a PR from another project that explains and fixes it: https://github.com/zxh0/vscode-proto3/pull/73

I had this same issue and realized it was because I had set my default formatter to Prettier in my user settings. So prettier was trying to format my elixir files instead of vscode-elixir-ls.

Okay, well if you figure it out please report back! Best of luck 😃
