No shared folders in Windows 10 guest

[sunrider]

Host: Ubuntu 22.04, kernel 5.15.0-119-generic

Guest: Windows 10, 22H2, OS build 19045.4780 and 19045.4894

VBox 7.1.0 just installed

guest additions 7.1.0 installed in above Win10 guest

After the install of the 7.1.0 guest additions, shared folders are no longer found. Windows network discovery finds VBOXSVR, but no network drive shares. Manual network drive mapping also fails.

I have another Win10 guest, still with the 7.0.20 guest additions, running on the same host. With the old guest additions the shared folders are available.

Please provide a patch ASAP or a guest additions 7.0.20 fallback iso image. Thanks!
