403 Forbidden error

I have always had access to Nextcloud and suddenly in the middle of a day I was uploading files to it when I got the error that you can see from the following printout (first time seeing this error):

Nextcloud version: 25.0.4
Operating system and version: Debian GNU/Linux 11 (bullseye)
nginx version: 1.18.0
Apache version: 2.4.56
PHP version: 7.4.33

If anyone knows of a solution please indicate as I need to fix this error as soon as possible.
Any information/file you need please let me know as I am not the most experienced person in this.

As stated in the message your Apache webserver is unable to read the .htaccess file. Check the file access rights and make sure that the webserver is allowed to access it. Usually it needs to be owned by the user under which the webserver is running.
