File not found immediately after sharing?

Nextcloud version 24.0.3
Operating system and version Ubuntu 20.04)
Apache or nginx version Apache/2.4.41
PHP version PHP 7.4.3

The issue you are facing:

Is this the first time you’ve seen this error? Y

I share a file via the share menu. Making a normal link but the link is immediately expired.
Certain folders do work (which as it happen are all on the external storage added disk). But when I use my main folder so to speak, I get the error of file not found etc. COuld there be like a blockade on sharing certain folders etc…?

The output of your Nextcloud log in Admin > Logging:

Nothing about sharing or fitting in that time frame, only about the successful update

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

I...somehow can't find it... even though the LOG etc are there (which I guess is the install location?)

The output of your Apache/nginx/system log in /var/log/____:
