[Bug]:After updating to NC30, files are not always displayed in folders (it seems to be a problem with the frontend display)

Bug description

After updating to NC 30, everything seemed to work fine at first, but then I started noticing that the frontend is becoming unresponsive and freezing. I've observed that not all folders are displaying their contents correctly. Sometimes, when I enter a folder, it appears empty, but after some time, files reappear when I enter the folder again. I don't know how to fix this issue, and I'm not sure where to start looking for the problem. Nextcloud is installed on Ubuntu 22.04 LTS.

At first, there were issues with the Office integration, so I disabled Office. Then, I disabled everything except the recommended applications. The performance improved, but the issue with file display still persists.

I'm asking for help—are there any specific details or information required for analysis?

Steps to reproduce

Try accessing different folders; some open on the first attempt, while others require re-entering several times.

Expected behavior

I expect a recipe for salvation.

Hi @ad-tomsk:

I'm sorry to hear you're running in challenges.

The logreader errors look like nextcloud/logreader#1330 (which was not a bug, but a configuration matter).

From what I see of the other errors visible, I suggest posting on the community help forum to troubleshoot the problem(s) a bit more (we're not equipped to provide general troubleshooting/configuration assistance via this channel).

You can reach the help forum at https://help.nextcloud.com.
