Also happen on photos.

I'm having the same issue. Brand new install of NextCloud AIO. I uploaded about 100GB of photos. Whenever I click on the "Photos" link, NextCloud freezes completely. I have to restart the NextCloud container.

This is what I'm seeing in the logs.

OCP\Files\NotPermittedException: Could not create folder "/appdata_ocpq51zbx1fh/preview/5/d/a/0/4/d/6/34800"

When I disable the Photos app, the problem goes away. I've read through multiple threads online, there doesn't seem to be a solution to this.

This issue also happens on my instance which is on Nextcloud 25.0.12.

What happened here (and on another old issue)? An "Unknown user" (who had a name a few days ago) marked this as solved (not planned)?

[joshtrichards]

They were the OP. They removed their GH account and closed a bunch of their original issues just before doing so. I re-opened the ones I'm aware of.
