java.util.concurrent.CancellationException

I'm very regularly having this exception when using Psalm. I've seen similar issues reported here, including several Psalm-related, but not with this particular error.

I'm using PhpStorm 2020.1.2 (build #PS-201.7846.90) with the latest version of the plugin (1.6.1). Psalm is set up using standard configuration described here.

Same here with Psalm (vendor/vimeo/psalm/psalm-language-server):

Can confirm that I am getting this with using elixir-lsp
