Have the same issue :(

For non-admin users in WebUI for GorupFolders folders list renders by browser as general URLs for every folder:

For admin - URL does not displayed in the bottom left corner of browser (uses Vue?)

Edited:
So, when non-admin user clicks on the folder, browser tries open URL:
https://_NEXTCLOUD_URL_/remote.php/dav/files/_USERNAME_/_FOLDER_NAME_
and get downloading file named FOLDER_NAME.htm contains
This is the WebDAV interface. It can only be accessed by WebDAV clients such as the Nextcloud desktop sync client.

But when I open the same folder as admin, URL in the browser's address bar is:
https://_NEXTCLOUD_URL_/apps/files/files/_FILE_OR_FOLDER_ID_?dir=/_FOLDER_NAME_

Have exactly the same issue. The same operating system. All fully patched. Nextcloud 28.0.5. On the nextcloud client all is working as expected. The problem exists only in the Webui.
Hope you fix it as soon as possible. My users complain about it.

This bug is still present on Nextcloud 29.0.0 with Groupfolders 17.0.0.

I don't know what happens, but I don't face this issue at the moment.

The same Nextcloud v28.0.5 and Group Folders v16.0.6. I haven't update Nextcloud and the App because of waiting for issue confirmation and fix release.

It may be not related, but when I saw the issue (7th of May) there were several Errors in Nextcloud Log regarding webdav: InvalidPath File name is too long. A user tries to sync veryveryveryveryvery long name file using Nextcloud Desktop WIndows client. We fixed that on 13th of May.

This bug is still present on Nextcloud 29.0.3 with Groupfolders 17.0.1.

I am unable to reproduce this behavior. Are you sure there are no other errors appearing in your Nextcloud log around the same time (likely just prior, such as when the Files page is loaded for tendering)?

Also, can you check your browser inspector, specifically the Console and Network tabs for errors, transactions that aren't green, etc. This may provide further clues.

Are you all using Apache?

At least for me the problems are resolved by disabling the LibreSign app: LibreSign/libresign#3351

As long as the others doesn't experience the described problems without having LibreSign installed, the issue can be closed.
