Discussed this issue with @stephendonner @MadhaviSeelam and added release/blocking and put it in the 1.66.x milestone as this doesn't reproduce on 1.65.x. We should resolve prior to releasing 1.66.x. cc @rebron @kjozwiak for visibility and in case you feel differently - we can adjust labels/milestone 👍🏻

It seems like it could be a caching error, but I'm not sure. Does it repro in another profile?

Reproduces 100% in a clean profile, for me.

from brave-browser.

Gotcha! On my intel machine, it was reproducible. I suspect something was wrong while rolling out the beta. Maybe webpack dependency? But not sure who can look into this. (Niglty works fine)

from brave-browser.

Going to be interesting to see what happens when the new Beta comes out. Hopefully this just disappears?

I checked but my dev version was okay. We're asking folks about the build machine here https://bravesoftware.slack.com/archives/C01EVLWS8R5/p1713744910635809

@stephendonner not sure but can we get a build artifact from https://ci.brave.com/job/test-brave-browser-build-macos-x64/1189/ and see if it repros?

So this doesn't repro for me in 1.66.80 in Linux. However, we've been seeing a few of these ChunkLoadErrors which is worrying me a bit. I wonder what's causing them.

On my mac, both beta and nightly works well.

I'm worried it's a build/installer problem. Does reinstalling the same version change anything @stephendonner?

I think it's using Morpheon Dark: https://chromewebstore.google.com/detail/morpheon-dark/mafbdhjdkjnoafhfelkjpchpaepjknad (now that I've retraced my steps); can you and @sangwoo108 try installing that, and see if the new-page page/Customize dialogs are broken/

from brave-browser.

Hmmm, still works for me - that would've been a neat solution though. Does it work for you when you remove it?

It'd be weird though, 'cause I don't think extensions can run on chrome:// urls

I wonder if this could be related to the React 18 upgrade

from brave-browser.

Yeah, it works for me with the theme(Nightly)

@stephendonner I'm cuirous what you see when you type "chrome://newtab/314.chunk.js" to the location bar? And also curios if you're uising intel mac or arm

@sangwoo108 here you go, thanks for asking!

Interesting, I'm not sure it should be same but my beta returns different source for the address. I've checked using my arm machine. I'll try checking using intel mac and let you know
