How the change has been tested

You need to look at this PR as an attempt to make it unlikely that the blank screen issue occurs, and if it occurs to increase the chance that the app is in a state in which you can continue developing. High chance that the fixes do not cover all corner cases.

I tested by removing node_modules and installing dependencies several times, which should trigger Vite dependency optimizations. There should be none because of the dependency inclusion list in vite.config.ts.
