Symfony encore watch and vscode Remote SSH development freeze the server when running at the same time - symfony

Question

I'm developing my Symfony project on a remote server and use Vscode Remore SSH plugin to writing code on it.
I use symfony Webpack Encore to build front side, and if I try to run commands like yarn encore dev or yarn watch to let webpack to rebuild my assets when vscode is working and connected to the server all freeze.
Web pages become loading very long time, vscode cannot save anything and the command line may show sting Running webpack ... without any results a minutes or throw an error like this
[webpack-cli] Failed to load '/var/proj/veto/webpack.config.js' config

When vscode doesn't work webpack's running without any problems. When I'm writing and saving code and do not use webpack all works great either.
I have very few ideas how can I fix it. How may it be related?
I tried to turn off vscode plugins that may scanning the project, but it didn't help
