How much is your RAM?

I am having the same issue with 16Gb of RAM. I deleted the contact us and product pages from the website setting and suddenly CSS is broken.

Can you run

bench build 
bench clear-website-cache

and try again?

Yes, already tried that. Logged the problem as https://github.com/frappe/frappe/issues/13480

Thanks for your suggestion, it is the correct first step

Hi, Ram will not be related to lost css, use chrome in developer mode to see the errors, you will see calls for .css and or .js are broken.

You build seems to have failed.

Hello @mcd.steven , Please were you able to overcome this?

I am also stuck in this page, could you please tell us how did you overcome this?

This worked for me.
Rebuild the css
bench update --reset
