Locking the drive sharing user in the workgroup ....

Question

A strange problem has arisen in a workgroup network with one PC with Windows 11 operating system and several PCs with Windows 7 operating system:
When we share a drive on a PC with Windows 11, as soon as other systems are connected and the user name and password are registered and the drive is mapped, the Windows 11 user is locked and does not log in even with the defined password.

I think that the new security level of Windows 11 for access restriction creates this problem, but I did not find a way to fix it.

Version and build of Windows 11
It is 22h2 (os build 22621.900).

I would be grateful if someone could help me.
