Issue

I'm still seeing crashing when running the web app locally. Looking closely at the error message, they suggest updating the memory limit on ForkTsCheckerWebpackPlugin

Solution

Looking at the docs for ForkTsCheckerWebpackPlugin, we see that the default limit is 2GB. Let's bump it to 4GB

Testing

I was able to consistently reproduce the crash in cea-desktop with these steps:

• Checkout main and run yarn start
• Checkout an old version git checkout 1.504.0
• Wait several seconds and observe the crash

We can verify that this fix works by:

• In cea-desktop client, open node_modules/tea-react-scripts/config/webpack.config.js
• Apply this change to that file (add the line from this PR)
• Repeat the above test of checking out main and switching to an old branch
• Verify that the crash no longer occurs

Note that you should still expect to see unrelated compilation errors due to the significant difference between the two versions of the code base. However, the crash should not occur.
