Suggestion from communities tried

Creating a local user with RWX rights to drive
Sharing the drive
Restarting the computer :-P
Resetting the docker for Windows
Switching from and to Windows and Linux containers
Reinstalling Docker for windows
Disabling Firewall/Antivirus Software

but nothing helped!

回答1:

The culprit was SAMBA encryption. With encryption disabled it works great

Bug: Unable to share C drive #1637 https://github.com/docker/for-win/issues/1637

Bug: Encryption disabling is not an option nor SMB below 3 #5342 https://github.com/docker/for-win/issues/5342

But it's not recommended so in current edge releases of Docker for windows has moved away from SAMBA.

so installing Docker for Windows Edge 2.1.7.0(41536) or later resolved the issue.

You might face switching to edge channel from stable 2.1.0.5 (current)

Bug: Docker Desktop on Windows unable to switch to Edge #4672 https://github.com/docker/for-win/issues/4672 (OPEN)

You can uninstall the stable release and download the edge release from https://docs.docker.com/docker-for-windows/edge-release-notes/

for me installing Docker for Windows Edge 2.1.7.0(41536) solved the issue.
