Files missing - fresh production install

Did a production install on existing bench installation using

bench switch-to-master
bench update

Got errors:
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (erpnext-web.min.js, line 0)

Hello @Bhaskar_Jain,

I think source may be corrupted so, download new bench repo and frappe bench.

Thanks

@Bhaskar_Jain

Try:
bench watch

if its not work then try:
bench update --reset
