theia: Getting error on start: internal/modules/cjs/loader.js:638 throw err;

Description

I am building an IDE on Theia for a month now and it’s working completely fine until three days ago when my Theia application just wouldn’t start. It builds normally, but it doesn’t start.

yarn start:browser and yarn start:electron both are having issues.

Reproduction Steps

To reproduce, please follow these steps:

1. Clone Theia repo
2. Run yarn
3. Run yarn start:browser or yarn start:electron

Versions:

Node: v10.20.1 NVM: 0.35.3 NPM: 6.14.4 OS: macOS Catalina 10.15.4 (19E287) [latest]

Solutions already done

I have tried every single solution that I found on the internet regarding this issue. I also uninstalled and installed Node and NVM twice. But that didn’t help.
