Using Umbraco 8.6.1 and everything has been going fine until the other day when the backend stopped showing up once logged in. I had recently changed the password for the account, but not sure why this would case the issue. The login is actually successful but nothing shows up.

In my console there was an error about it not being able to find angular-chart.min.js.map but that seems to have dissappeared now. I think it could be something to do with ClientDependency but tried tinkering with various settings, deleting TEMP folders and so on... no luck. Gone through various threads on here about similar issues but found nothing that's worked.
