Describe the bug / error

I have a default modern team site connected to a Teams Team with a plain document library.
I've added a couple of menu-items in the Quicklaunch with address/link to a subfolder in the document library.
When clicking the menu-item it sometimes opens the library with the subfolder, sometimes opens the root of the library, and sometimes gives an error telling the elemt is moved or deleted.
The browser showses correct address - refreshing the browser bringes up the correct content - library view with the subfolder

Steps to reproduce

1. Add a menu-item in the Quicklaunch menu with address: /sites/sitename/libraryname/foldername
2. Save and refresh
3. Click the menu-item addressing the sub-folder several times and click different menu-items

Edited:

I tested in another site, and there it works fine.
Difference when checking in dev tools & network treffic:
The failing site uses SP.List.GetListDataAsStream and params TryNewExperienceSingle: TRUE and listFullUrl that includes foldername

The working site simply requests the address from the menu-item.

Expected behavior

Expect to get the library view with the correct folder/subfolder every time user clicks the menu-item

@jikleveland,
For my tenant it works fine.
I am able to successfully navigate into the folders via the Quick Launch menu without any issues.
