Do you still have the problem ?

In my case it was a reverse proxy issue. Nginx was not able to found this app assets resulting in a blank page.

Hm, I have exactly the same issue. Running Nextcloud 17.0.1 in a docker container. All apps and settings work, just SSO & SAML for some reason shows a blank error page.

@lunika when you say it was a reverse proxy issue - could you tell more about it? Thanks!

//Edit: This is the error message I can see in Chrome:

Refused to execute script from 'https://<myurl>/apps/files/' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

I'm facing the same problem with Nextcloud 21.0.0 after installing user_saml plugin. This errors arise at the browser console: .../apps/dashboard/” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff)

Any hints on how to fix this?

Sorry I didn't comment my fix earlier. For me it was simply a file permission problem. Double check if all PHP files belonging to Nextcloud are executable and all directories Nextcloud needs to write to are writable. Die MIME error is misleading and came from the reverse proxy in my case, as the reply did not match what it expected. The Nextcloud logs have been helpful for me
