Unable to reproduce and based on the behavior and error this looks like a configuration/filesystem/image matter in your environment. It appears you're using LInuxServer.io's Docker image[1] (not the community Docker image). Perhaps something went wrong when you transitioned to their new image structure[2]?

Since this isn't a bug in server or the community Docker image, I suggest posting over at either the Nextcloud Help Forum[3] or the LinuxServer.io Forum[4] if you need help troubleshooting.

I have the same issue using the official nextcloud:28.0.1-fpm Docker image. The downloaded File download.php.html contains the following line.
Fatal error: Uncaught Error: Class "OC_Util" not found in /var/www/html/apps/files/ajax/download.php:31 Stack trace: #0 {main} thrown in /var/www/html/apps/files/ajax/download.php on line 31

See #42617 (comment) for an update.

It does not apply for non-nginx proxy servers. I have been running a docker version fpm-alpine with Caddy as a proxy and the only dirty hack for now is to hack the download.php file directly as it misses includes for some reason. See #42617 (comment).
