R7800 Readyshare doesn't work on Windows 11

I have two Netgear routers. One main R7800 and the other R6400v2 connected to it via patchcod operating in AP mode. Both are connected to 2.5" drives via USB. On Win10, access to the USB drives is problem-free, mapping works fine. On Win11, I can't map drives from R7800 - it displays the message "An extended error has occurred". However, I can map a drive from R6400V2. Interestingly, the system does not remember credentials despite selecting the "Remember login credentials" option (you have to enter login data every time you start the system to access the resource) and you can't map a resource by router name, e.g.: \R6400v2\DISK2 - it only works by IP address, e.g. \192.168.1.1\DISK2. Both routers and the computer are in the same workgroup. In the Win11 network environment, R7800 is visible but R6400v@ isn't. SMB1 is enabled, Insecure Guest Login is enabled. I reset the network settings and it doesn't work. What could be the reason for the lack of access to the USB disk on the R7800 via Win11?
