Bug: "The parameter is incorrect"

[HarryAdney]

Description

Trying to pin a folder to the sidebar, but This modal pops up every time. It's not the only thing that causes the error message appear, just the latest one I've found.

It happens in the stable (3.9.1.0), and preview version: 3.9.12.0
Windows Home Pro: 10.0.19045.0

Steps To Reproduce

Right-click a folder > Pin to sidebar
Error message appears

Click and drag to sidebar
Error message appears

This happened over a year ago when I first installed Files, but I uninstalled it because of this error. I reinstalled recently, but the error still occurs.
¯_(ツ)_/¯

Files Version

3.9.12.0

Does this apply to all folders, or only a specific one? Does it work if you pin it via File Explorer?

Thanks yaira2. It included all folders but I hadn't even checked if it affected File Explorer too, which it does. I can't believe I missed such an obvious check!

Anyway it was just a matter of deleting the Quick Access Cache:

1. Close File Explorer completely.
2. Open Run (Windows key + R), type %AppData%\Microsoft\Windows\Recent\AutomaticDestinations and press Enter.
3. Delete all files in this folder.
4. Restart File Explorer and try pinning the folder again.

Works great now. Many thanks.
