Login page not loading properly after version upgrade

Nextcloud version: 21.0.2
Operating system and version: Archlinux
Apache or nginx version: nginx 1.20.1
PHP version (eg, 7.4): php 8.0.7

After one of the version updates, web interface of Nextcloud doesn’t seem to work properly anymore.
I’m facing following distorted screen on any browser I try:

Nextcloud itself appears to be working just fine as client is successfully syncing files and doesn’t show any errors.

There are no errors in Nginx log, just the same 2** and 3** you see in the browser.

I’m not really sure where to look further… Is it in some way corrupted or something changed making old config incorrect?

Let me know if you have any ideas.
