Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can 
Nextcloud version (eg, 20.0.5): Nextcloud AIO v7.0.0 (Nextcloud Hub 5 (27.0.2))
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04.3 LTS
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.57 (Unix)
PHP version (eg, 7.4): PHP 8.1.22
The issue you are facing:
Nextcloud freezes when opening nextcloud photos and scrolling down, or opening nextcloud memories (even without scrolling). I have about 4k files including mostly pictures and some videos, and they take up about 170 GB of storage. Once nextcloud freezes it stops working completely, and you can’t perform any action at all. If you refresh the page the request times out. On my Android phone it doesn’t load either. While it’s frozen, the resource usage on the server is very low (<2 GB of RAM in use out of 16GB and the CPU usage is at <5%).
Is this the first time you’ve seen this error? (Y/N): N
Steps to replicate it:
- Freshly install the latest version of nextcloud AIO
- Copy a bunch of images and videos to the data directory of a user
- Run
occ files:scan --allto index all the files - Install nextcloud memories (not sure if this step is necessary)
- Open nextcloud photos or memories (it happens with both)
- Scroll down until nextcloud freezes and stops working completely until you restart the
nextcloud-aio-nextclouddocker instance.

I’m not sure what this is asking for, please clarify
Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.
Many errors like these, they look the same (I beautified the JSON to make it easier to read):
