Windows Admin Center / External virtual switch

Hello,
In the Windows Admin Center I can't add a external virtual switch.
When the center load the network adapters, I've this error :
"Unable to load network adapters. Error: RemoteException: Unable to validate argument on parameter "Message". The number of characters in argument 36227 is too high. Shorten the length of the argument so that it is "32766" characters or less, then try again."

I've remove hyper-v, type "netcfg -d" reboot and install again hyper-v but same problem.

The operating system is Server 2019 core 20h2.

Thank you in advance.

I found the solution.
In fact, I don't have connect all my network cards.
I've deactivated in device manager the cards who not are connected.
Now I see the different network cards.
