Big Sur Beta 7 breaks SMB?

After the upgrade from Beta 6 to Beta 7 I am not able to connect to any smb-shares any more. I tried it with a Windows Server, Synology DriveStation and a Debian implementation. I'm directly getting the message Error with connection.

Unredacting the logs reveals the issue, insufficient permissions to load the kernel extension. Just run this (once):
sudo kextload /System/Library/Extensions/smbfs.kext

Hello, it is Beta 6 (20A5364e). I experienced the same behavior and I just submitted a Feedback report. It seems afp protocol is still working.

Terminal cmd line also does not work to mount an SMB share unfortunately. Big Sur Dev Beta 6.

I can confirm the same thing on my end. As of 20A5364e, I can no longer connect to SMB share located on macOS Mojave 10.14. No login screen, no delay, just an immediate generic network error message.

Same here .... Just installed Beta 6 and all SMB shares immediately pop up with "Connection Failed" message. Any ideas?
