### Bug description
We got weird "operation canceled" errors according to the Nextcloud Desktop App.. While I do NOT see these kind of errors on the server side.
Going back to a older version (like desktop client 3.13.3) directly synced, no errors, no issues! And yes using the same server. Meaning we have a regression issue here (especially when there are large amount of files and folders on the server and client, the latest desktop client just fails hard).
---
Server side Nginx access log (_no_ errors in the error log of Nginx), and even no errors in Nextcloud logs, which actually seems fine:
```sh

```
Also _NO_ related errors in the Nextcloud log either. The errors you do see in the nextcloud app seems to be unrelated I believe.
---
The same sync errors are happening on both the Deb PPA as well as the AppImage. Meaning it doesn't matter which way you download the latest desktop client, it's _not_ a packaging issue.
### Steps to reproduce
1. Use NC30
2. Use a account with a lot of folders and sub-folders and files (I guess this just helps)
3. Use the latest desktop client (v3.14.0)
4. See "Server relied with an error while reading directory <...>: Operation canceled" messages, while the server actually DID replied!
5. **Reverting** back to Desktop client 3.13.3 _solved_ all my sync issues! Meaning this is a huge regression issue. After I first downgraded and now upgraded again to 3.14.0, the issue is not present anymore. Meaning 3.14.0 was unable to resolve the client-side issue, while 3.13.3 was able to solve the issue.
### Expected behavior
I do not expect regression with regard to the latest desktop client version (3.14.0). While I do _not_ experience any issues by _downgrading_ to 3.13.3 (v3.13.4 should also work).... After I downgraded and I now upgrade again to 3.14.0 and do NOT see the issues anymore..
Which doesn't mean that 3.14.0 is stable, it just means that whatever the error was, 3.13.3 and 3.13.4 could resolve the problem while 3.14.0 could NOT.

### Additional info
Related tickets: https://github.com/nextcloud/desktop/issues/5356 (it's an old ticket, while now I can pin-point exactly the issue between two desktop client version causing regression).
I'm happy to share the archive debug log, but not in public. I hope you understand.
