<myorg>.awsapps.com/start Slow Initial Loading Time

I have been experiencing an issue with the site at <myorg>.awsapps.com/start. The initial loading time of the site is exceedingly slow, taking over a minute to load. Upon investigating the issue using my browser's developer tools, I found that the 0.js file has a large size of 4.9MB, which appears to be the primary cause of this slow loading.

Although subsequent attempts to load the site are much faster due to the caching of the 0.js file, the initial loading time is still a significant inconvenience for users who access the site for the first time or after clearing their cache.

The file in question is located here: https://d19soru4bzonzg.cloudfront.net/assets/Prod/us-west-2/20c348129a138e5db7e872c0d89ad4a7/0.js

It is indeed inefficient to load such a large file before the user even logs in. A more optimized approach would be to defer loading non-critical resources until after the user has logged in.

Can anyone suggest a solution to address this issue?
