Icloud very slow with Windows 11. Windows Search problem??

I recently updated Windows 10 to Windows 11 22h2 and now I have a problem with Icloud.

If I navigate through the folders with File Explorer using the left column everything works fine.

If I navigate between folders with the main window I have to wait 8/10 seconds to open one.

The same time it takes to open a simple text file of a few kilobytes.

I have a high-performance PC with I5-14600 32GB RAM DDR6 NVMO Samsung Pro and 1GB internet connection

The Icloud folder is set to "Keep files on this device" so all files are local and not in the cloud

I then thought that the problem might be the lack of indexing of Windows Search.

I then noticed that if I customize the folders to be indexed in the settings of Windows Search, the "c:\users\Antonio\IcloudDrive" folder does not appear in the list.

The folder obviously exists and if I check its properties it is also flagged "Allow content indexing"

What could be the problem?
