Help with binding a Python interpreter to an SSH server about pycharm restart

I am experiencing an issue with configuring a Python interpreter via an SSH server in PyCharm.

Initially, I successfully add a Python interpreter based on an SSH server, and it works correctly. The interpreter is properly bound to the remote SSH server.

However, after restarting PyCharm, the SSH-based interpreter configuration disappears. When I try to reconfigure it, the SSH server selection option becomes unavailable — I can see the interface asking me to select an SSH server, but the dropdown is disabled and I cannot select anything.

At first, the configuration interface appears as shown in the second image (where the SSH server is properly configured). But after restarting PyCharm, it changes to the first image, where it asks me to select an SSH server, yet the SSH server option cannot be selected at all.

Has anyone encountered this issue before? How can I fix it?
