Shared folders get `(2)` at the end of the name after update to 33.0.0 RC1

Hello.

After updating to Nextcloud Hub version 26 Winter (33.0.0 RC1) from Nextcloud 33.0.0.11 beta, all the parent folders shared with me were automatically renamed with the same name followed by a space and (2) at the end of the folder name. The same thing happened in previous beta versions updates.

Regards.

Same here. Shared folders get (2) at the and of the name and each access (which gives "file not found") increases the number of (2)s

See here: https://cloud.mrjive.it/index.php/s/eDtTL6xi2HbDi5N

It affects both files and folders.

Thanks!

Our case.
The problem appeared only for one user, after updating 31.0.13 -> 32.0.5
Problem at the intersection of Collectives and File Share
To reproduce the problem you need:

1. User1 share file1 to User2
2. User2 move file1 to Collectives folder
3. All shared files to User2 become to add name ' (2)' every UI request
4. file1 in Collectives User2 is doubles. And can't do anything (move/rename) with it.
   Helps only DB editing or remove sharing file1.

There are also many errors in the database:

detail: "Key (user_id, root_id, mount_point_hash)=(User2, 123456, 8ffeda918c334cd61e32cb7ef8ccd07n) already exists.",
